We are selling a lot of 50 Custom shotshells for the 72 caliber / .7283″ air rifles. These are made with lead shot and a very hard injection mold jeweler’s wax. They typically stay in one piece on soft targets (and penetrate), on hard targets they shatter. The average weight is around 600 grain. After April 18th, 2022 I will have a YouTube video up showing these and the similar 50 caliber shot rounds being used on ballistic gelatin.
