What loader? What is the setup? I have had issues with my ULE detents being in too far and getting bolt stick/chuffing from that. This even happened with an SHP reg. Unfortunately, the faster you get, the more fine tuned things need to be. I finally have one of my markers RTing like a beast with an SHP reg, but it took me a fair amount of time to get it set up JUST right. And even then, I occasionally have issues.
