THE UNLOVED .25s

Craig Boddington

Yes, that title will upset some folks. Funny thing about the .25-caliber cartridges, bullet diameter .257-inch: Those who love ‘em tend to be passionate about their “quarter-bores.”. Those who don’t love .25s probably don’t hate them, just ignore them.

This big feral hog dropped in its tracks to a single 100-grain Interlock from a Savage 1899 in .250 Savage. The old .250 Savage isn’t fast, but it’s as effective on deer-sized game today as it was a century ago.

The .25-caliber is a uniquely American bullet diameter, rarely seen in Europe, equally uncommon in Africa. I’m told the .25-06 has some following in South Africa, but I’ve rarely seen a .25 in use on safari.

Over here, the quarter-bores have a rich history, going back to the dawn of smokeless powder. The .25-20 was created by necking down the .32-20 case to .25-caliber, first by Marlin, then by Winchester, and chambered in their popular 1892 lever-action. Initially loaded with blackpowder, the .25-20 quickly transitioned to smokeless. Although occasionally used for deer, the little .25-20 was a common small game and varmint cartridge, popular among trappers.

On a Kansas deer stand with a Winchester M94 .25-35, made in 1906. Because of iron sights, Boddington is careful which stands he chooses, but he does a “sit” or two with this rifle most deer seasons.

Winchester’s .25-35 was the first .25 designed for smokeless powder. The .25-35 and .30-30 use the parent same case, and were introduced together in 1895, so were the first sporting cartridges designed for smokeless propellent. Although hampered by round-nose bullets in tubular magazines, the .25-35 shoots flatter than the .30-30 with a less recoil. The .25-35 was a common alternative to .30-30, plenty of gun for deer-sized game. Jack O’Connor’s outfitter in Sonora in the 1930s, Charlie Ren, used nothing but a Savage 1899 in .25-35. O’Connor famously quoted Ren as saying it was “all he needed.” Lord knows how much game that rifle accounted for.

In 1915, Arthur Savage engaged early cartridge genius Charles Newton to develop a high-velocity cartridge for his lever-action. Newton’s project for Savage resulted in the .250-3000 (.250 Savage), the first commercial cartridge to break 3000 feet per second. The Savage lever-action was stronger than the Winchester, and its box magazine could use sharp-pointed bullets. The .250 Savage was popular for decades…and a real thorn in Winchester’s side.

Gunwriter Gary Sitton was another huge .25-06 fan. He used his Dakota M10 .25-06 to take this fine buck on John Wootters’ South Texas ranch, “Los Cuernos.”

In 1920, Savage introduced the M20. Essentially a scaled-down Springfield action, it was not only America’s first commercial bolt-action; it was the world’s first short bolt-action, sized specifically to the .250 Savage case. In our Kansas deer season just past, Ryan Paul brought a cherry M20 and shot does with it, first M20 I’ve ever seen in the field.

The only way the .250 Savage could reach 3000 fps was with its original light-for-caliber 87-grain bullet. 1915 expanding bullets worked when they worked, but most hunters learned that the .250 Savage performed better with 100-grain bullets at about 2800 fps.

Wyoming gunwriter Bob Milek in the field with one of his beloved .25s. Milek used both the .257 Roberts and .25-06 for game up to elk. Boddington doesn’t believe the .25’s have enough bullet weight or frontal area for larger game, but with proper shot placement, they surely work.

Gunwriter Ned Roberts necked the 7×57 case down to .25-caliber, creating the .257 Roberts, adopted by Remington in 1934. Its longer case enabled heavier bullets at higher velocity than possible with the .250 Savage. Until the .243 came along, the .257 Roberts was the standard “crossover” varmint/big game cartridge. Although rarely chambered in new rifles today, it was extremely popular, and remains an important cartridge.

The .25-06 was developed at Frankford Arsenal during WWI as a military experiment. After the war, it remained a common and popular non-standard wildcat. Amazing to me none of the majors picked it up sooner, but it wasn’t adopted as a commercial cartridge until 1969, as the .25-06 Remington. To this day, the .25-06 is the most popular .25-caliber. With heavier bullets, it is fast, flat-shooting, powerful, and awesome on deer-sized game. With lighter bullets, the .25-06 is probably the largest and most powerful cartridge that could sensibly be used for varminting.

Boddington used his Dakota .257 Roberts with 117-grain SST to take this weird Kansas “management” buck. The buck went down so fast and hard it seemed to bounce.

The .257 Weatherby Magnum was one of Roy Weatherby’s original cartridges, introduced in 1944, based on a necked down and shortened .300 H&H case. It is one of the fastest and flattest-shooting of all commercial cartridges and was Roy’s personal favorite. It’s not especially popular; a limitation is that it has remained a Weatherby proprietary, thus limited sources.

In recent years there have been few new .25-caliber cartridges. An exception was the short-lived .25 WSSM. Great little fireplug of a cartridge, about the same performance as the .25-06, yet from a much shorter case, fitting into short actions. Several of the short, fat magnums introduced at the turn of the millennium have fallen by the wayside. Mostly, I put this down to “too many, too fast.” Too many new cartridges for the market (us) to accept. The “super short” magnums were so short that feeding problems occurred in some platforms.

For the record, I’m not a huge .25-caliber fan but I neither hate them nor ignore them. I have a long history with .25s. In the early ‘70s, on a cougar hunt, the houndsman handed me a Colt Lightning slide-action .25-20. Since then, I’ve hunted with all of them, even tried the .25 WSSM when it was new. I had a super-accurate .25-06, used it a lot, have had a couple of .257 Weatherby Magnums. As a lever-action buff, I’ve had a succession of .250 Savage rifles, have a good one now, made in 1920. Also have a 1906 M94 in .25-35. My current favorite .25, however, is a Dakota M76 in .257 Roberts, accurate and sweet-shooting.

This blacktail was taken with a .257 Weatherby Magnum. By far the fastest commercial .25-caliber, the .257 Wby shoots flat and hits hard.

I admit that I’m not passionate about .25s, but friends that I’ve respected have been. Great gunwriter, friend, and mentor Bob Milek was a quarter-bore guy. He loved the .257 Roberts and .25-06 equally. Gary Sitton, one of our greatest gunwriting talents, was also a .25-06 guy. My longtime boss at Petersen’s HUNTING, Ken Elliott, was a .257 Weatherby Magnum guy, thought it was the cat’s pajamas. So did Robert E. “Pete” Petersen, founder of Petersen Publishing. Sadly, all these guys are gone. Scott Rupp, one of the best Editors I currently work for, is still with us. He’s a quarter-bore guy.

Tastes in cartridges are often somewhat reginal. Usually, this is driven by game hunted, and by local hunting conditions. Texas is the great stronghold of the .25-06. Hard to find a Texas deer camp where somebody isn’t toting a .25-06. Medium-sized deer, shots often on the longer side. More than that: A common landform there is long, open cuts between brushlines, the famous Texas senderos. Here’s the thing about hunting a sendero: They’re narrow with few reference points. When a buck steps out he may not stop for long. No time to mess with a rangefinder, quick look at antlers and shoot. A flat-shooting .25 is a near-perfect choice.

In 2023, Ryan Paul brought a Savage M20 to Kansas, first time Boddington has seen an M20 in the field. An aperture-sight rifle, Paul used it to take does, using a scoped rifle for his buck.

In Central California, we hunt small-bodied blacktail deer. The .25-06 is popular here today, but, historically, I think the .250 Savage was a top gun. I say this because, for years, it was easy to find Savage 99s in .250 on almost any used-gun rack. In the .250 Savage’s heyday, we didn’t yet have feral hogs, and in our tight canyons, shots on our blacktails are rarely long. The .250 Savage was an ideal choice.

For me, the .25s are excellent for pronghorns and deer-sized game, questionable for larger game. Others disagree. Bob Milek used his .257 Roberts or .25-06 for elk almost every year. Milek was a Wyoming resident, usually looking for a fat cow or young bull for the freezer, rarely seeking (or taking) mature bulls. In that context, fine. For all-around elk hunting, I draw the line. Can work just fine, with caution, but I don’t think the .25s offer either the bullet weight or frontal area for general use on game larger than deer.

A nice Central Coast blacktail, taken with a .25-06 on a Ruger M77 action. Accurate and flat-shooting, the .25-06 is the most popular .25-caliber cartridge, a great choice for deer-sized game.

If there’s a fly in the .25-caliber ointment, it’s a bullet problem. Like our traditional .270 cartridges, the .25s have always been considered hunting cartridges. Historically, there have been almost no match-grade bullets or loads in .25-caliber. Today, with the rage for range, little development of modern, low-drag .257 projectiles. As with older .270s, part of this is a rifling twist issue. Since the 1920s, standard rifling twist for .25-caliber cartridges has been 1:10, stabilizing bullets from about 70 to 120 grains. Maximum G1 Ballistic Coefficient (BC) for the most aerodynamic 120-grain .257 bullets is about .400. Not bad, but not in the same league as the modern low-drag bullets with BCs well over .600.

We need longer, heavier .257 bullets to get there, but our 1:10 barrels won’t stabilize them, and many of the actions on our .25-caliber rifles won’t house them. There are some options out there. Berger makes a 133-grain .257 bullet, and Hornady has a new 134-grain .257 ELD-Match with G1 BC of .645. Undoubtedly, these choices will grow. However, none of my .25s will stabilize these bullets. I’m not interested in rebarreling. Same story as my pet .270 Winchesters regarding the new, heavier .277 bullets.

Two different approaches to varmint rifles. Left, a Savage .22-250. Right, a .25-06 on a Ruger M77 action, both with adequate accuracy for any varminting. Boddington believes the .25-06 is the most powerful cartridge that makes sense for varminting.

Doesn’t matter to me. I’m not an extreme-range guy. My .25s shoot well enough and flat enough for my purposes. Happy to keep them in their box as awesome, light-recoiling choices for deer-sized game, at shooting distances I’m comfortable with.

DON’T OVERLOOK THE ‘06

Craig Boddington

A writer friend was in black bear camp this past spring, shooting a .30-06. At the sight-in range, younger hunters gathered to admire his rifle. They’d heard of the .30-06…insisted they’d never seen one.

By about 1930 the .30-06 reigned as America’s most popular hunting cartridge, holding this position for at least 40 years. Times change, but I’m shocked there are grownup hunters who have never seen or given passing consideration to the .30-06.

46 years after his first safari, Boddington still believes the .30-06 is among the best and most versatile choices for Africa’s non-dangerous game. This fine waterbuck was taken in 2019, using a left-hand Ruger M77 with 180-grain Hornady Interlock.

In 1903 the United States military adopted the Springfield bolt-action rifle, mated with a rimless bottleneck cartridge firing a .30-caliber (.308-inch bullet). Rifle and cartridge were so close to Peter Paul Mauser’s designs that Uncle Sam paid Mauser a royalty until WWI. The original 1903 cartridge used a 220-grain round-nose bullet. In 1906 the case was modified slightly, the bullet changed to a lighter spitzer with greatly improved aerodynamics. The new cartridge was called “Caliber .30 US Government Model of 1906.” We soon shortened that to .30-06.

The first sporting use of the .30-06 doesn’t seem recorded. Well-known is that Theodore Roosevelt swore by his Springfield throughout his epic nine-month 1909 safari. At that time the lever-action was America’s most popular sporting rifle. There were no domestic civilian bolt-actions at all until 1920.

.30-06 velocities vary considerably among manufacturers. With 165-grain bullet, Hornady’s Superformance load yielded 3016 fps…that’s edging into .300 magnum velocity.

The Savage M20 was America’s first bolt-action sporter, Sort of a mini-Springfield, it was sized for the short .250 and .300 Savage cartridges and could not house the .30-06. The first American sporter that could was Remington’s M30 in 1921, based on the big 1917 US Enfield action. Winchester followed in 1925 with the M54, forerunner to the M70 (1936).

Shortage of commercial rifles didn’t deter the .30-06. Surplus US Enfields and Springfields were cheap and available. The supply from both world wars lasted through the Sixties. My own first centerfire, purchased in 1964, was a surplus ‘03 Springfield. I think it cost $39.95. I didn’t hunt with it until years later, but I shot it a lot, and lovingly “sporterized” it.

We hear about new cartridges being inherently accurate, but don’t sell the ’06 short. This lightweight Kimber Terminal Ascent produced sub-MOA groups right out of the box with the first load tried, Federal 180-grain Trophy Tip bonded bullet.

Starting in 1925, the flatter-shooting, softer-kicking .270 gave the .30-06 competition but never overtook it. Even Jack O’Connor, high priest of the .270, conceded that the .30-06 was more versatile. The first magnum craze of the Fifties and Sixties eroded the .30-06. I bought into that stuff; I had a .264 and a .300 Winchester Magnum before I hunted with a .30-06.

Although she later switched to a .270, Donna Boddington did most of her early hunting with a left-hand Ruger M77 .30-06. She used a 180-grain Hornady Interlock to drop this excellent Mozambique sable with one shot at sundown.

I read my Roosevelt, and my Hemingway, and my Ruark, so when planning my first African hunt I knew I had to have a .30-06. I trotted down to the PX and bought a Ruger M77 and worked up handloads with 180-grain Nosler Partitions. Even though I’d been a confirmed magnum maniac (“magniac”), I was amazed at how well the .30-06 performed. All ranges, all sizes of plains game. Became, and have remained, a .30-06 fan.

The flood of unbelted magnums at the turn of the millennium gave us new choices. Recent cartridges designed for maximum efficiency (PRCs, Noslers, Westerns) give us more options. Today we have plenty cartridges to choose from. It’s easy to overlook the .30-06.

The .30-06 probably isn’t an ideal mountain cartridge, but it shoots flat enough. Grancel Fitz took his first sheep, a Dall sheep in Alaska, in 1935 with his Griffin & Howe Springfield. 20 years later, he was the first person to take all varieties of North American big game…all with this same .30-06.

Old, but not tired. The .30-06 is a powerhouse. Standard issue for our forces for 50 years, the .30-06 is the most powerful cartridge adopted by a major military. Not as fast as our many magnums, it is not slow. Standard velocity for a 180-grain bullet is 2700 fps. In perspective: The same speed as the 6.5mm Creedmoor…with a 140-grain bullet. With 180-grain bullet, the .30-06 offers 28 percent more bullet weight…with .044-inch more frontal area. There is no comparison in hitting power.

Wife Donna did her early hunting with a Ruger M77 .30-06. Not the same one. I was doing a lot of hunting with a left-hand action M77 .30-06. Also a lefty, she’s shorter, so I took a sliver off the butt and reset the recoil pad so we could both shoot it comfortably.

Sadly, not all new rifles are chambered to .30-06. This is Chapuis’ new ROLS straight-pull, made in France…with .30-06 among its many chamberings. So far, out of the box accuracy is about one MOA…not unusual for good rifles in .30-06.

Now, let’s be clear. The .30-06 is not a low-recoil option. Generations of recruits complained about the brutal recoil. They were not wrong. Donna is one of those people who is uniquely impervious to recoil. In general, I don’t recommend the .30-06 for youngsters, for women of smaller stature, or for anyone with aversion to recoil.

To this day, the (nominally) 2.5-inch of the .30-06 defines “standard-length” actions and cartridges. Factory cartridges based on the ’06 case include, left to right: .30-06, .270 Win, .280 Rem, .25-06, .35 Whelen, .370 Federal, .280 AI. Boddington believes the .30-06 is still the most versatile of all.

The .30-06 is a big gun, needlessly powerful for any deer hunting. It is a far better elk cartridge than deer cartridge! I still have magniac tendencies. I see the medium magnums, typified by the .338 Winchester Magnum, as the most ideal elk cartridges. Yes, but the .30-06 is plenty of gun for any elk, especially with today’s great bullets. I’ve taken as many bull elk with the .30-06 as with magnums. None have gone farther, most down in their tracks. Because of heavier bullets with more frontal area, I think the .30-06 is more effective on elk than any of the 7mms.

One of the advantages to the .30-06 is lots of loads…and lots of handload recipes. This Savage 110 .30-06 grouped variously with different loads…and then shot quarter-inch groups (bottom center) with Federal factory with 180-grain Barnes.

The .30-06’s strongest suit is versatility. Awesome for larger game, such as elk and moose. I still can’t think of anything better for the full run of non-dangerous African game. The .30-06 kicks but lacks the bone-jarring recoil velocity of the fast magnums…and it works.

Versatility isn’t just about size of animals. Today’s newest cartridges use faster rifling twists with extra-heavy bullets with super aerodynamics. The .30-06’s traditional 1:10 twist stabilizes bullets from 150 to 220 grains. How much versatility do you need? For deer, a 150-grain bullet zips along at 3000 fps. For elk, and for Africa’s variety, I’ve always been a 180-grain bullet guy. I’m not keen on using the .30-06 for big bears, but more grizzlies and brown bears have fallen to the .30-06 than all the rest put together. Old-timers relied on the long, heavy 220-grain slug, which can be loaded to 2550 fps, credible velocity for such weight, offering wonderful penetration. I also don’t recommend the .30-06 for extra-large beasts. However, in the days before minimum legal calibers, the .30-06 with 220-grain solids had a great reputation for reliable penetration all the way up to elephant.

The .30-06 is probably needlessly powerful for deer…and also dramatically effective. This big Colorado buck was dropped in its tracks by a single 180-grain Fusion bullet from an ’06 made by Kenny Jarrett.

Maybe it’s also not the best choice for mountain game. As with deer, .30-caliber bullet weight and power aren’t essential for sheep and goats. I’ve taken both with the .30-06, but I’ve usually chosen cartridges that shoot flatter. Not because I needed them, but because they seemed a better “fit.” Once you get to the point where you must either hold over or start dialing your turret for range, trajectory is just a number. Know the number and you can solve the problem.

I’ve done a lot of 1000-yard shooting on steel with various .30-06 rifles and loads…as have long-range competitors for 120 years. Once you start adjusting, a few more clicks is a matter of knowing how many. I’m not an extreme range shooter on game. If I were, then there are better tools. However, because that’s what I was carrying—and because I knew the trajectory—I’ve made some of my longer shots in the field with the .30-06.

Boddington believes the .30-06 is a wonderful elk cartridge…and better for elk than deer. This bull dropped in its tracks to a single 180-grain Barnes TSX at about 150 yards.

Many of our newer cartridges offer great versatility on game, at varying levels of recoil, and are often touted for accuracy. Cartridge design matters, but rifle, barrel, and ammo are more important. It’s an article of faith that the .308, with its shorter, more efficient case, is more accurate. Maybe, but the margin is slim. I’ve rarely seen accuracy problems in a .30-06 rifle. With higher velocity, the .30-06 is more powerful, thus more versatile.

So many choices, so many conflicting and confusing cartridges. Here’s one good reason why the .30-06 may be worth your consideration. Availability. Everybody loads .30-06. It is no longer our most popular centerfire…but it’s still in the top handful. There are hundreds of factory loads, from all manufacturers, throughout the world…offered with just about any bullet you can think of. No, these days, we can’t get them all. But the .30-06 is not a one-company wonder, as new cartridges must be until they catch on. For handloaders, we have a century of loading data to fall back on. Can’t get this powder or that bullet? Plenty of choices.

Willem van Dyk, trackers, and Boddington with a big fringe-eared oryx, taken in Kenya in 1977 on Boddington’s first African hunt. This was the first time Boddington hunted with the .30-06; impressive performance made him a lifelong fan.

Just yesterday, I went to the range with a new Chapuis ROLS, a fine, state-of-the-art straight-pull rifle. Made in France…chambered to .30-06. Finding the best load for this rifle is still a work in progress, but the loads I grabbed randomly from my garage grouped within one MOA. That’s performance I expect—and usually get—from a good .30-06.

Not all great new rifles are chambered in .30-06. I suppose that’s a sign of the times. Explains why some younger folks consider it a curiosity. For sure, it’s not as sexy as the hot new numbers. It’s still an accurate, powerful, and versatile choice. And the .30-06 is still out there, hundreds of loads, jillions of rifles…of all vintages.

.270 versus 7mm: Too close to call!

Caliber .270, bullet diameter .277-inch, is primarily an American phenomenon based on the .270 Winchester, which was introduced in 1925. Its origin is murky; there was an experimental 6.8mm Mauser developed for China so rare that standard references show no photos. No evidence confirms that Winchester was even aware of this obscure cartridge.

Jack O'Connor ram 270 Winchester — Jack O’Connor with one of his last rams, taken with his famous Biesen-stocked “No. 2” .270. O’Connor was the undisputed champion of the .270 Winchester, but from the standpoint of years I have to agree he was right!

Nobody knows for sure why Winchester’s Roaring Twenties engineers settled on that bullet diameter. They probably wanted something based on the .30-06 case that might shoot flatter, kick less, and be almost as versatile. There were other options; both the 6.5mm and 7mm (.264 and .284-inch) bullet diameters were popular in Europe and making inroads in the United States, but in xenophobic post-WWI America, using a “European” diameter might have been out of the question.
