327 Federal Magnum 20 Rounds Ammunition Speer 100 Grain Jacketed Hollow Point

I have tested this ammunition in my LCR 1.875" and it did quite well. I have a Youtube channel where I test ammunition for velocity as well as ballistic performance through my test medium (4 layers of denim followed by 1.75" bologna followed by 1/4" medium density fiber board followed by 6 water jugs). The 5 shot average velocity from the LCR at 12 feet from the muzzle was 1,398 FPS for 434 ft lbs energy. The damage to the bologna pack was right on par with the Gold Dot .357 Mag 135 gr short barrel I tested from a 2" barrel. The penetration was hitting the back of the 3rd water jug which is exactly how far all perfect performing ammunition penetrates to (equivalent to 15" in ballistic gel) and the bullet expanded to .537" with no loss of retained weight or fragmentation. It did quite well and was really impressive. The only down side I found (which is probably why it's not loaded in nickel plated cases) is that the brass expanded a lot more than .357 Magnum, so case extraction was a tad more difficult than normal, but not bad enough to be a deal breaker. It's overall pretty effective .327 Federal Magnum ammunition.
