I was wondering if any of you guys have used any 33wcf brass from quality cartridge? I bought some to load for my dad for a gift and have a concern. I noticed that to get the correct headstamp on it they turned the face where the original stamp was in the lathe until it was removed, then they re-stamped it 33 win. My concern is when they did this it made the rim about .020 thinner. This cartridge headspaces on the rim correct? So will this cause a problem in the gun, like the firing pin won't be able to go in far enough to ignite the primer, since the primer would be setting .020 farther forward? Thanks guys.
