You can go on Amazon and get .22 Ramset loads which work great in the Heritage Rough Riders...
Doubt a .22 barrel bore would look quite right for the camera. I just meant .45 cal blanks for camera and .22 for live plink rounds. No chance the Uberti could take a live .22lr by mistake.
Seeing live .45 colt ammo on set should have set-off alarm bells for armorer.
