I am loading 9mm on a Dillon 650 using starline brass, lead powder coated semi-wadcutter bullets and using a mr. bullet feeder. About 10% of my cartridges wind up with just a little shaved lead at the mouth of the casing that prevents them from dropping into my chamber checker like they should. Sometimes I can take a wire brush and remove the lead and then the cartridge will fit in the chamber checker, but not always. I run these cartridges in my Glock 34 pistol and my Ruger PCC 9 carbine. The Ruger will swallow all I make even the ones that did not fit properly in the chamber checker but the Glock is a lot more picky and will only cycle and chamber a perfect round.
I suspect that the Mr. bullet feeder is not dropping the bullet straight onto the brass and it will allow some lead to be shaved off the bullet. I do watch the to see if the bullet is straight in the case but I don't think I am being finicky enough and some are tilted just enough that I don't realize it and don't try to adjust it. I am using the Dillon powder funnel and have tried lowering it to bell the mouth more but this didn't work. I am going to get the powder funnel from Double Alpha and see if this cures the problem.
Has anyone here had this same problem and was the use of the DA powder funnel the cure?
