So I have a Colt AR that started as a standard LE6920 (16" w/ 1 in 7" twist rate) and since then I free floated the barrel and did some other minor changes as well as a 4-12x p-223 scope. My plans for the rifle were to be a decent bench and coyote gun. I played around with some 50 & 55 grain factory loads as well as some hand loaded 55 grain rounds loaded down to around 2800fps due to the higher twist rate. Anyways, I'm really disappointed with my accuracy out of the gun, I feel pretty lucky if I get 1 MOA out of the thing. I've been shooting since I was about 5 and can almost put them through the same hole with my .17 or .308 so I dont think my user error is all that bad. With the tight twist I was thinking of trying some 69 grain Sierra Match Kings or Berger's. Anyone have any advice or think a heavier bullet may help?
