My question is, what is the normal practice in this situation? I plan on taking sized cases, neck sizing only in a 9 x ?? die and loading some gas check 9mm bullets to start.The neck will need to be annealed every few shots to keep down splits, but shooting the 9.3's will really raise pressure and there was so much lead squeezed off while slugging that it has to hurt performance. Does this approach sound reasonable?
Once the cases are truly formed to the chamber on these long, straightwall cases, all you really need to do is resize just enough of the mouth of the case to hold the bullet firmly. I don't know that I would mess with annealing. But more than likely you are going to have to use filler if you don't use BP/Schwarzpulver.
There use to be a lot of choice in the 9mm(0.366") bullet area. It is the smaller 0.358", or whatever it is, where the bullet selection is narrow.
