After noting a thread on the subject here, I found data in an Alliant manual and gave it a try. I loaded two loads, both with the Lee 200 gr. round flat nose bullet. Both used 23 grains of Re-7. One load was with Win. LR primers, the other with Fed LP. I was surprised at the difference. The load with rifle primers averaged 1300 fps on the nose, and groups were about as good as I've had with this rifle - about 2.5" at 70 yds. With pistol primers, it was a different story. MV was 1150, and the one group I shot was 7". ES was 50% bigger with the latter load too. (I don't have my data book at hand.) The 1300 fps is about as fast as I want to go in my original '73 Winchester, so I think next I will try backing off a grain, and loading with LR mag primers.
