Acorrding to Elmer Keith, use a felt over powder wad - unlubed - and you can leave it loaded for a very long time. Now, as far as home defense is concerned,best first line of personal defense would be EXTREMELY BRIGHT LIGHT try one of those 2 or 3 million candle power hand held spotlights, along with a co2 powered air horn like boaters carry or sports fans use. the blinding light and PAINFULLY LOUD noise will disorient and frighten intruders. and if you made a mistake and intruder is family member, cost is only new underwear for them, and no hospital bills. As far as fire arms go, forget hand guns, fine motor skills go away when you go into fight or flight mode. This ain't here say, I've experienced this myself more than once. If you must use gun, get shotgun loaded with the smallest shot you can get, up close it'll do the job without going thru bad guy, and wall and kids room, and exterior wall and neighbors wall, get my point? One last thing,we live in lawyer heaven, if you dont go to jail, you still might be sued and bled dry. Talk to a local cop and a lawyer. hope you never need to use force.
