Back to the range today and I remembered the calipers. Was able to tighten the group on the .270 to .445" with OAL. Seems to like .020" and .025" off the lands. Got the kids .243 out shot a ladder with it. found one that shot .782", but haven't confirmed it yet. Some really wild groups with it. I think some of it was because I had to shoot it much faster and couldn't let it cool much between groups like I usually do.
