6.5 Creedmoor 20 Rounds Ammunition Sellier & Bellot 140 Grain Full Metal Jacket

If you have a semi-auto this is your best ammo choice. Think about it the distance between the bullet tip and the casing shoulder is longer than the barrel extension. This means your bullet tip is likely to encounter the chamber counter bore or the feed ramps. Either way this contact will impact the tip concentricity and thus accuracy. The S&B FMJ is the most resilient tip you will find in this caliber and not subject to this type inaccuracy. The muzzle velocities are very consistent. Usually around 0.7 MOA at 100 yards. Try the Hornady white tail SP for comparison and you get a 7.0 MOA because of this effect. In a bolt gun the price performance is great and the casings are very good quality for reloading. Hope they make a 6mmCM the problem is even more prevalent there.

I was pleasantly surprise at the quality and accuracy of the S&B 6.5 CM ammo. I had read review about problems extracting and poor over quality. I had none of these. The ammo out of the box looks as good as any I have purchased from other companies. When fired from my new Ruger Precision Rifle I got groups well under MOA at 100 yards. Now I have gotten smaller groups from this rifle with other ammo but the ammo cost twice as much as the Sellier & Bellot. I will be purchasing more.
