Yup. The powder coating you're using is adding to the dimension of your bullets making them too large for the chamber of that particular rifle. Gp

43PU I have two 300 B.O.s a Handi rifle and an AR upper, neither will accept a bullet who's nose is larger than .301 and that's tight. I either shade the noses of the bullets when I powder coat them or nose size using the Noe system. Gp

Does this happen when you chamber a round or just pulling bolt back across magazine?

Chamber jam is evident, crimp is super much. Could be a chamber loading scrape/feed problem.

I'd seat them down to the crimp groove and use a lighter crimp. As for the brass, the third lug of the bolt riding over the rounds in the mag, perhaps.

I'm surprised you're not getting more damage after pulling your boat back across those things......:bigsmyl2::bigsmyl2::bigsmyl2:

I would not worry about the bullets, look at the ring around the case in front of the web. Almost looks like a case head separation waiting to happen.

Good for noticing, but these are made from blanks!! From one of our members here!! They are awesome for the price

AR or Ruger mag? Either way, I'd suspect too much follower pressure. Also check the bottom of the bolt for machining marks/burrs that need to be polished out.

is the PC being removed most of the way around the first band or only in the portion pictured .. If all/most of the way around PC'ed drive band is larger than chamber
