Im getting ready to start reloading for my nef 4570. (Im brabd new to reloading). Ive been looking at bullets. Can Yo use any 45 cal bullet or do U have to stick with .458. Im sure that info is in the books, but Im still waiting for reloading stuff in the mail. BTW I ordered the lee classic loader.( First step ) plus I ll be able to take that to the fire station & reload.
