So I didn't really think about it until some ammo manufacturers started coming out with the crimped bullet (or whatever it's called) that prevents the bullet from sliding back into the brass... If my cartridges don't have that feature, how many times can I chamber a bullet before its no good? I line up my carriages every few days now to make sure they are all the same height... But I did notice they are getting scratched up... Wanna kill these ads? We can help!
