[QUOTE="BrentM, post: 864149, member: 61747"] OK, good info guys. Thanks BMF for the feedback. I am well within the zone of the berger manual and keep thinking I have issues with pressure signs. The biggest issue I had was at 57.5 grains I was getting the occasional flyer. I reduced the charge in .5 increments to test accuracy at .75 off the lands, my normal load. I found 57 strung vertically and 56.5 was solid .25 MOA with no flyers. I then played with seating depth and found a little more accuracy at .100 off the lands and left it alone. I just thought it was strange the speed would go considerably up and yet the case is not indicating the pressure has increased on the case head as much. I did find that the ES was much better with bullet seated to the lands vs at .100. In fact I had 2 in my test that flew 2953 and 2954. In another test they flew 3000 and 2999. Next time out I have more time to tinker and record results. This was just a test I wanted to try while dialing one of the kids 7mm-08 for the up coming hunt. [/QUOTE]
