Federal Tactical and your factory flush fit modified choke will do it. That should throw about an 8"-10" pattern at 25 yards. Don't use a wad stripping choke with the Federal load. Federal uses a Flite Control wad that is designed to stay with the shot keeping it all together longer for tight patterns. If you can find the Federal Tactical #1 Buck you're in business. Number #1 Buck is under appreciated, it's the best anti personnel buckshot load on the market.

Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats.
