I used my 11-87 for deer hunting for a few years and even have a real nice buck on the wall that was shot with it. When I used mine I just shot Brenneke rifled slugs through the imp. cyl choke tube. This was not a long range set up. Usually my shots were 50yds or less. If you really want to get serious you'll probably want to put a rifled barrel on it and shoot some type of sabot slug.
