I have many Slug Guns, of course my Savage 220 hands down is my #1 gun, 3/4" groups at 100 yards, 1.5" groups at 200 yards. But I do have two 1187s with the rifled/cantilever barrel topped off with Leupold VX-II 3-9x40......The 12ga Accutips 2-3/4", the 20ga 3" Accutips, and both shooting great, not as tight as the Savage but very accurate
