Quote:Remember when you use your caliper as a depth gauge to set the base on a flat hard surface and open the gauge so that the extension is even with the rest of the bottom of the caliper. It may account for the .005" that you are missing. I saw someone else post this, and had never considered it when measuring depth.
Good idea. I will try that. I will also chambering a few and measuring before and after OAL. I will also put some black marker on them. I def wont be shooting it anymore. It will be going back.
Edit: Tried zeroing on a flat surface. No difference. Still measuring .130 bolt face dept. I am going to chamber some in a few minutes.
