Well, that's the problem. They run great in the factory barrel, but I've poked around the internet and found about firing lead through the factory barrel, and about the really large factory chamber that allows a bulge at the base of the case.....
I seated the bullets just a tad deeper and tightened down on the crimp and seems to be working pretty good now. It is pretty sensitive to the way I grip it, so if I don't cinch down on it, it won't lock up all the way.
Accurate beyond belief, though!
