I just got my rifle and first reloaded some 405gr hard cast .459 boolits and bought some factory loaded 405gr jacketed .458 boolits. The rifle shot pretty well at 25 and 50 yards, but the factory was supposed to be about 1330 fps and my reloads using IMR 3031 was supposed to be 1250-1300 fps. What I noticed was that the lead boolits had more recoil than the jacketed boolits. I was curious if the difference was mainly due to the sized boolit difference or what. Both were well under the published 29007 cup limit by Pedersoli.
