Re: How many neck sizes can you get away with?
see i dont like my primers seating really easy like that, i just loaded up some of this brass again, and i think i might only get one more loading out of it. i decide when, when using my lee hand priming tool takes hardly any pressure to get them in, also look at your bolt face and c if there is a black ring on the face if so, the pockets r worn out and gas is getting by so then i'd say the cases r done. i dont know about the velocity of your load though. i dont have a chrono and dont know the speed of my load.
