So you think the bolt is gouging the the top of next round to be chambered while cycling back. Obviously since the bolt never touches the bullet on it's way to the chamber.

The bolt will always rub the top of the next round while cycling. It's the nature of the beast. If it's causing excessive gouging then either the bolt is in rough shape (maybe dropped since it's a new problem) or the rounds in the magazine have too much angle (magazine is splitting in half towards the feed lips).



edit:

Wear where?
