I bought a bag of wax bullets, modified shells, and shotgun primers several years ago. I may start using these to do a little practice. I haven't shot many of them yet but they seem to function fine in my 6" Ruger Security Six. The shotgun primers are a little loud to shoot in the yard.
POI is about 2" below POA at around 5 yards.
I don't have any ties to the business, but included the business card in case anyone has the desire to contact them.
