For a Mossberg 500, I've read a lot of posts, and heard a lot of advice from people who say avoid the 15 pellet Magnum 12-gauge 3" shells with 00 buckshot, especially if you're pimpin' a pistol grip and an abbreviated (but legal) barrel. Go with 8 or 9 pellets, not 15 with a Magnum fuse. The recoil will rock you cross-eyed, they said. One guy even promised I'd need an arm brace. Your thoughts? Experience? Advice? If you had to knock a patch out of someone's ass with a Mossberg 500 Persuader, what shells would you use? And I'm not worried about over-penetrating the sheetrock or singing the precious wallpaper.
