Congrats on getting into stamp collecting.
The 2 needs you have expressed, 223 AND 22lr could not be further apart, unfortunately.
A rimfire can needs to be taken apart to be cleaned. The VAST majority of Rifle (223) cans are sealed.
The other issue is size. A 223 can will be 3-4 times the size and WAY heavier. Its just not practical to have one can for both.
