Morning Boys & Girls

Would anyone be able to tell me what gun/guns that CCI No 10 percussion caps fit please ?

Ive cleared my Dads place and brought a lot of kit home including his stock of BP stuff he had a Pietta NMA once but also a Ruger OA too

My Ruger Old Army takes No 11 or RWS 1075s so these are too small.

Cheers
