Looks like the .22 wad punch on that company’s page isn’t available yet. Give them a call and say you’d like to do some “prototype testing” with one of their pre-release units; maybe they’ll ship you one to try. Couldn’t hurt...
LOL! Maybe!
I’ve been using a spent .223 casing and pounding it with a hammer to punch out cereal box cardboard to make wads but it doesn’t last very long before it bends.
It’s been so much fun having a backyard air shotgun to keep the house sparrow and starling populations down.
