I have a RAR in 7mm-08...shoots handloads great. It only likes Hornady American Whitetaill factory ammo.
I have a RAPredator in .223. Only likes handloads. Factory ammo I have tried was terrible groups.
No issues with the trigger, magazines, or stocks. Mine are set ~3.5lbs. I was able to adjust them down where I wanted with no issues.
