Home Forums Hunting & Shooting AR and Tactical Rifles 1st shot out of group with RR Predator Pursuit

I had a GAP 10 and was getting lousy groups from 175g FGGM. At one point during my shooting session, I pulled a loaded round from the chamber and pulled the bullet out of the case in the process. The inertia from the bolt closure had moved the bullet forward into the barrel where it became stuck. (Just like a kinetic pullet puller.) For whatever reason, I had a batch of FGGM with inconsistent neck tension and was getting inconsistent COAL during chambering.

Solution: Once the gas system has been tuned, the solution is to crimp or increase neck tension.
