Can get more velocity but bug hole accuracy happens for me in one rifle that has a 26" barrel with 49 grs IMR 4350 with a CCI 250 mag primer in a Rem. case 3000 fps average. It does the same with 117 Sierra Pro Hunters. In a 24" rifle 52 grs H4831, CCI BR-2 primer, Rem case 3000 fps average. Have killed deer out to a touch over 500 yards with no problem.
