I bought this 500 grain bullet mold before I read where 500 grain bullets are too long for repeaters. (Duh, my usual way of learning, after the fact.) It's fine for single shot rifles and carbines, so if you're looking for a cannonball for your 45-70 single shot, this should fill the bill! $40. You may also text me at 678 994 9732. Joe-Ed New
