I’m developing a load for my 10mm gen 3 Glock 20 sf. I e worked up to 9 gr of unique using 155 gr xtp. Crimp is .420-.421 and oal is 1.260-1.261. Chronograph at 1388 FPS from 8 feet. Inside of casing after firing looks good. It’s functioning good and I don’t think I’m pushing it too awful bad but I’d really like to hear from those that are more familiar with this type of combination. Casings show a little bulge but I understand that is common and normal with these chambers. Please advise
