The gun is heavy and ungainly, and, I really wish I had the same magazine for my M1A, but here is what 18 rounds did at a hundred yards.
The shots up at the top of the target are from my lever action 357, but the big ragged hole at the bottom was from 18 shots out of the DPMS AT-10.
The ammunition was what I believe to be Austrian military surplus, and 2 out of the 20 rounds failed to fire, despite what looks like good firing pin indentations. I've never had any issues with this rifle otherwise.
I just still can't get over a 50-round magazine for 308....
