[QUOTE="BillyGoatGruff, post: 2460283, member: 63346"] 68.4gr was where it hit pressure today. I had hit pressure at 69gr last week. Weather conditions similar. Probably within a few degrees temperature wise. The vertical stringing came on two depths of a seating test .050" off and .075" off. Using 67gr. But they were the best groups of the seating test. I chose 67. Because from my earlier pressure test I had from 66.5-67.5 had similar velocities. Just took the middle to perform the seating test with. I'm going to test both sides of the better seating depth in smaller increments Trying to get rounds down the tube so it can speed up/stabilize or whatever and get into my once fired brass before I really start fine tuning the powder charge I have a solid rear bag and shoot off a bench rest up front.
