I've done enough testing 30
years back with shot handloads in a .45 revolver to determine that
they don't really have any utility for anything I'm likely to do. The
donut effect is still there and a one-piece .45 Colt slug is still
likely to be a lot more decisive than a shower of shot.

The "donut effect" you described has been more or less minimized in the
Judge. They only very lightly rifle the barrel for the purpose of
keeping it a unlicensed handgun, and it does quite well with the pattern.

I've shot skeet with it (close.. 10yd).
