Blew through another 200 rounds today but can't hit shit..noticed the can and barrel are moving quite a bit. Gonna torque down the PLA barrel nut, hopefully it doesn't crack

When you cock the bolt back, does the whole bcg moves back and causing a gap between the feed ramp and barrel? Chamber a round and eject it and look at the bullet is it deformed might be Causing it to keyhole.  I had that problem and made a spacer so the bcg doesn't move back causing a gap and deforming the bullet.
