Roger that! I'm working on a pellet probe right now, about 90% now, but I have to go visit a buddy's shop tomorrow to try to get the right size cutter. in addition to setting too deep in the barrel and the transfer ports not lining up, the main body diameter of the pellet probe is a few thousandths smaller than the carrier bore it sets in. 2 1/2 - 3 thousandths may not sound like much, but in this application when you tighten the set screw it pushes the probe off center and leaves a rub mark in the brass chamber on the end of the barrel.
There is some opportunity for a smith here, or even better for the factory to step in and take ownership. with the barrel and pellet probe out, I can look through the gun and see with a naked eye that all of the bores are not in alignment, and what I see also shows up as a rub mark on the barrel. This thing should be assembled with a precision ground arbor, holding all of the components in perfect alignment until they are tightened. Or, line bored after assembly.
