I made a bunch of 10mm defensive rounds for my Glock 20, and I am looking to get educated on case inspection.
I fired two rounds from a Glock 29 with a stock barrel. About 3/16" up from the rims, the cases are now expanded from about 0.420" to about 0.433". The primers are flat with the bottoms of the cases. There are marks from the firing pin hole on the primers. I will post photos.
Does this look normal for this caliber and pistol? I've read that aftermarket barrels provide better support. I don't plan on reloading for self-defense, but I was hoping I could reuse the brass for target loads.
I haven't chronographed the loads yet.
The recipe is from Speer. I did not have CCI primers, so I'm using Wolf. The brass is new Starline.
