60 yards with a 20 gauge and an IM choke, no rifling needed. There is no reason your gun can't do as well.
I agree with Old Grump. You just have to find where the Foster Type slugs shoot to in your gun. Usually just about any shot gun is good to 50 yards or so, and I have seen them shoot good groups at 100 yards. My trusty old single barreled 12ga shot gun is good for 75 yards.
Y'all be safe now, ya hear!
