Easy solution if you're nutted up about cleaning the can is to get a user serviceable 223 can. Like a Lane, or Liberty Constitution.

Personally after seeing Hoser's test and talking to him about it. I bought a dedicated 22 can Just because I was planning on it anyway and I didn't want to deal with thread adapters, and or re-threading all my rimfire stuff. But unlike all the internet gospel I did buy a Thunderbeast 22L because it's light, wicked quiet, and I can throw it in the dip to clean it because it's Titanium. Yeah it's a sealed unit, and you can't take it apart, but I've shot their demo can that had an assload of rounds through it, and it's still damn quiet and it's not that much heavier. Plus, they'll clean it for you if you need.
