My garage has been turned into a home for rats in the last week or so. I have had no issues using ratshot loads in a 22 but they are out of sight in price. Even the cheapest ones are going for $22. for fifty. The only shot I have laying around is #9. At what speed should I push it? Planning on using aluminum can material for the overshot wad and paper plate or pop can cardboard doesn't really matter. Kind of don't want to do any more damage than the rimfire shot loads.
