Hi, this is my first post, my name is Jared, and I live in Arizona. Anyways, I bought some 10mm 200g WFNGC projectiles from double tap ammo. I went off of meathead9's load info and started low. Bieng the cautious person I am, I wanted to post a pic of the primers and get an opinion on whether or not they are overpressured, and if not, what signs would I be looking for when I begin to increase the powder charge? One thing I noticed was the "raised" area around where the firing pin struck, I was wondering if this was the from the primer moving back and contacting the firing pin hole/area. Also, I left the OAL at 1.26 because I didn't know if seating it lower would increase pressure. Any thoughts or suggestions will be appreciated. Thanks.

I bought some new starline nickel brass that I plan on using with my future 200g loads.
