[QUOTE="Stormrider, post: 565132, member: 6072"] I have a load that shoots1/2 moa in my rifles and a buddies... An M&P 15 16" bbl, an RRA 16" mid-length, and RRA Varmint with a 24" bbl. I used brand new LC brass, 25.3g of Alliant's AR15 Comp powder, any primer, I tested Federal SRP, Winchester WSR, CCI 450 and Remmingtion 7 1/2. Bullets were the 52 SMK, 52 AMax, and 53g VMax bullets. Primers made a difference in velocity but not accuracy. I never saw any pressure signs of any kind so I don't believe I'm close to the max but they are fast enough for me. All groups were shot with 10 rounds. Velocities measured from the RRAV 24" barrel. Lowest avg was 3030 and highest was 3273. Just as an aside, the most accurate bullet was the 75g AMax in all the rifles, it just had to be single loaded... [/QUOTE]
