And here's what I'm talkin' about:
The first two bullets in the group are the two left-most at ~50 yards(if you can tell the difference) and the third at a measured 100 yards was at the right of the group. Under 1/2" for the three shot group at two ranges. Kewl!
I didn't know the two shots at ~50 yards were touching when I asked my buddy (on his 4-wheeler) to move the target on down to 100 yards just to check POI. He didn't tell me until he came back with the cardboard box that had the target attached. By the way, in the cardboard you could actually see three distinct but partial bullet holes behind that cluster.
That faster twist might like these heavier saboted bullets just as well.
