Thank you.


That's not what I was getting at. It's the straight-ish part of the nose in front of the driving bands that can be a problem, depending on which version of the lube groove mold you got. I don't recall hearing anyone being happy with the tumble lube version in the 300 Blk. Powder coating these makes the problem worse too.

Best way to find out is to load up some dummy rounds and cycle them to figure out what works and what doesn't.


I see what you mean now. I was thinking that I may have to seat deeper to keep the bullet back from the leade, but on looking closer at the bullet, the section in front of the driving bands is darn near cylindrical. Only thing left to do is chamber the dummy round I made and see if it chambers properly.
