So yesterday I was shooting at 550-700 yards with both my M&P10 (TA11 ACOG) and Colt 6720 (TA31 ACOG). The 5.56 Colt shot amazingly with just M855, and I was consistently hitting the steel gongs that I was aiming at. Very happy.
The M&P10, however, was a huge disappointment. I was using cheap ZQ1 7.62, so I know that this is definitely not match ammo, but there was no consistency; using the same aiming point, I was hitting left, right, up, down, with some hits. Really not accurate whatsoever. I was there with another shooter, both of us experienced riflemen, and he had the same results.
I plan on stocking up on some Federal XM80 ammo and just relegate the ZQ1 for close range plinking. I know that even the Federal is nowhere near match grade, but that's not what I'm looking for; I'm looking for combat accuracy, like the M855, and something that I can stock up on without going bankrupt.
Anyone else have a similar experience with either this rifle or this ammo? Thoughts?
Here are both rifles for reference:
