You have a very fine rifle. It will shot cast bullets at full factory velocity with sterling accuracy. I have a 1959 Winchester 94 Carbine in that caliber. I use the RCBS 170 FNGC as well. Upon suggestion from a friend, I tried that bullet on top of 30/H335 and first time on the bench it turned in five shot one hold groups at 50 yards and 2 MOA groups at 100 yards. I have not tried any other power or charge, as I don't see that improving much if any.
