Quikdtoo, thanks didnt like reaming the screw hole but had, 410 bnarrel shoots 6" high at 15-17 paces but it sure puts a nice patter on a 2liter SunnyD bottle any critter is in trouble with, the 22 barrels shot really, seemed to shoot to POA but never targeted it, just walked around the woods and shoot/plinked. Put about 100 round thru it. Am going back up spend a week or so up there
