lol, appreciate the kudos. I'm a troubleshooter by nature, plus my real passion is firearms and handloading, so I have to screw with this kind of thing all the time.
The chops are all in the breech. None in the barrel. The barrel is a 14" J&J (not that it matters). Sadly, even in single fire mode I was able to starve the gun with the AK hopper. All I can figure is that it has to be all of the "bumps" molded into the feedneck. Since the Ricochet is already on it's way, I'll go ahead and order the feedneck in the next few minutes. Oh, and tank on the remote IS vertical. No snow.
