The tube needs to be rated for Hevi-shot, but yes, they work great for those designed for it. I've tried several, the Mad works the best of all including Briley, Trulock, Rhino. Comp-N-choke and 3 or 4 others that I tried. It's also the longest which probably has a lot to do with it. The 835 is overbore, that's why the tube is .695". I've made kills from 20yds to well over 50yds with it. I'd limit the shots to 40yds with lead shot as it doesn't have the pellet energy of Hevi-shot, even tho the pattern density is great.
