Couger: do you truly believe that a winter coat will stop a 000 buckshot at +- 1000fps? I use "Strike Threes" as my in-house load out of my Ruger Security Six 4" .357. It's three buckshot, three wound channels in under 2' at 7 yards. That's 21 buckshot out of a revolver, pretty good inside a house, like a shotgun in your hand. I have kids sleeping in other rooms, over penetration IS an issue.
