i'm new to alaska and new to the 460, but have been reloading for years. i'd like to work up loads pushing large meplat casts (360-395 gr) at slower speeds (~1200fps) in a 2.75 inch smith. i don't need the long range velocity, and i gotta believe a slower heavier bullet will do the trick while being more manageable. (am i wrong there?). there seems to be some discussion as to which primers to use in the 460-- large rifle vs magnum. anybody smarter than me have any suggestions where to start?
