Re: Soot on case necks
The short mags harden necks up in a hurry, how much are you having to size them down?
If you are sizing a lot, I would say try annealing a few and see if the problem goes away, if it does you will probably see more consistent velocities too.
Biggest question, how does it shoot...soot aside?
