As I stated earlier 52 gr H4831 or the SC version with a standard LR primer, preferable the CCI BR2, with the 117 Sierra Pro Hunter is usually very accurate. In most manuals this is the MAX load. My current rifle shot this load OK but shoots 49 grs IMR or AA 4350, CCI 250s in Rem cases with the 117 Sierra Pro Hunter better and at the same 3000 fps velocity. In my testing with my rifle IMR and AA 4350 shoot identical velocities and to the same point of impact. To prove this to my hunting buddy I shot two shots of each load at 300 yards into a group that measured 3/4" outside to outside. He could not believe it.
