Has anyone had any success in getting good patterns from these shells?  If so what is your gun choke combo?

I have some but I never patterned them. Bought them for shooting groundhogs along one of my fields where it's not really safe to use a rifle. They seem to roll the groundhogs pretty good out to 40 yards or so.
