I don't have any of those - do have some 120 BT & AMAX's that will be interesting to try.

The angle of the photo wasn't the greatest. Of the 10 rounds, I can count 7 in the main group, the last two of the group I pulled (range had a 'cold' before I finished and I must have changed my position). I either really shanked 1 or it is hiding in among the main group.

Hard to complain about 7-8 inside an inch (with shade) on a new rifle, with untried handloads, on a cold windy day - thus the title of the thread.

There are things that I could do better. The BT13 is too tall for the bipod, had to sit the bipod on top of a plastic parts box to get a line on the target. Will switch it to the BT12 I have on another so I can get a better grab on the bench. Wind had the target moving a bit, need to get a little better trigger discipline.

All in all, a most favorable experience. It wasn't cheap or always easy project - but it certainly pays off when everything comes together.
