Hi,
I was looking into buying some snap caps for a Schmidt-Rubin 1889 I have for display and demonstration purposes. The original 7.5x53.5 ammo hasn't been in production for a century, so there are no snap caps of that caliber. However, there are some in the similar 7.5x55 used by later Swissicon rifles. Would these be similar enough to work as intended since they don't actually need to be fired?

Thanks for the help.
