For practice and plinking, I use the 62 gr GI bullet & LC brass, w/ 25 gr of AA 2520 seated to mil spec length, from my 1:8 Bushmaster will hold just about 2 MOA, no crimp needed. The 55 gr factory ammo are decent but go about 5-6 in at 200 yd, IMI factory green tip will hold 4-5 in. The 69 gr Sierra over the same powder seated to mil spec will hold 3 in at 200.
