The first time I shot my 20ga USH I thought my 2 nd shot missed the paper. Upon review I discovered that the hole was slightly elongated. A 3 rd confirmed it. This was at 50 yards or so. The next shot was through the heart and lungs of a nice does at about 80 yards. 2 3/4" federals. I use 2 3/4" federals in my 12 GA as well. .
