Either, both will work. I'd probably use the rimfire can.

I was at a suppressor shoot and one demonstrator had a user serviceable can rated for 5.56. He had been using it on suppressed rimfire he said for 5K rounds. He showed us the dirty internals, put it together and did a 30 round mag dump from an AR-15. He then took it off, and the high pressure of the 5.56 rounds blew most of the residue off the baffles.

I'd only do this if your CF suppressor is user serviceable. It doesn't mean you won't need to clean it, you'll just extend the cleaning intervals out. I'd want an all stainless construction of internals as well to throw the internals in a hydrosonic cleaner, and clean the main body by hand to protect the finish.
