Even with the set screw turned all the way in the bolt still locked back and while it seemed to help the belted cartridges at first, when I switched to the second box of ammo they started getting belted again (all factory hornady 123 amax rounds)...I think I'll try to drill it out and put in a bigger set screw... right now it's only a 3mm screw... I'll try drilling it out to 4mm and see how that goes.
Well, it stands to reason that in order to block the gas flow, the setscrew needs to be at least the same diameter as the gas journal in the block.
