My dad use to buy RWS BB caps to use around the house for varmits and other things that aggravated him. We had three English Setters in a kennel out behind the house. Dads prized possessions. A neighborhood cat would agravated the dogs and dad had shot it dozens of times with a BB gun. One day he decide to sting it good with a BB cap. It was a good 30yds to kennel. He stung the cat alright, it killed it deader than a door nail. Don't under estimate BB caps. The ones with pointed bullets weren't called CB caps. I think they were called bulleted caps. Both came in round tins. We shot a lot of pigeons in barns with both.
