Yea, unless the centerfire can is user serviceable (can be taken apart for cleaning) don’t use it for rimfire, unless you don’t care if you ruin the can. It’s incredible how much crap rimfire dumps in a suppressor. Just go buy a rimfire can, they’re relatively cheap and atf approval is prettyquick right now if buying as an individual.

I tried uploading a pic of a rimfire can innards before cleaning, but all file uploads failed for me.
