[QUOTE="Hired Gun, post: 1298486, member: 1290"] What lube and dies are you using? For really hard brass I have found Imperial Case Sizing Wax will do things with ease that no other lube can touch. Your dies might need polished too. Those marks from the chamber should have zero affect on your sizing operation. More than a few factory firearms specify fluted chambers to ease extraction. Now to waste some bandwidth to have to say it or some DW will think I'm endorsing that chamber. I [U]do not[/U] believe this chamber was done this way on purpose. Most sporting and especially custom rifles have nice 320-400 grit polished chambers with no tool marks visible. That is an ugly chamber and terrible witness marks on the brass but I doubt this would ever cause you any trouble or shortened case life. (Not defending anyone but simply stating my opinion) To shorten case life the chamber would have to be grossly oversized or you pushing the shoulders too far back and this would lead to case head separations that all shouldered case brass are susceptible to when overworked.
