also having issues. filed it down and still having problems. it is picking up the next shell but getting jammed half way through the chamber
I polished the lever along with the bottom of the bolt where it engages. I squared off the notch in the bolt as it was a little rounded off. Beyond that I run it wet and it seems to work. I would like to get the bolt carrier coated with TiN or np3 so it has good lubricity regardless of the presence of oil.
