I already tried them. They are metric with a larger internal measurement. Couldn't find an American wad that didn't give me bloopers. I know they make Euro style wads that would probably work but, I like to keep my loading operation simple. If I can't load it with an American wad IMO it's too much trouble but, to each his own!The ones made in France load even better, in many "euro trash" scrounger's opinions. You should try them.
