Like allaroundhunter said; you're really looking for at least two cans here: a .30 caliber can and a .22 can.

Most center-fire rifle cans are sealed, meaning you can't take them apart: You don't need to clean a center-fire rifle can and they work better if they're sealed and can't be disassembled. The pressure is high enough that almost all the carbon fouling is blown right out of the can, and the thin layer that remains helps protect the baffles from heat and pressure and makes the can last longer, but this thin layer of carbon doesn't get too thick because of the huge amount of pressure going through the can with every shot.

But if you shoot .22 through it, the lead will build up and be almost impossible to remove. Eventually it will get thick enough to affect performance and it's almost impossible to remove the lead from inside a sealed can. This is why most people don't shoot .22 out of their rifle cans.

My favorite .22 can is the Spectre 2: super durable (rated up to 5.7), super quiet, and super easy to clean (not quiet as easy as the Sparrow, but with much less first round pop).

And my favorite rifle can is the AAC SDN-6. It's a full-auto rated .308 can that also works really well on 5.56. It's also optimized for subsonic 300 blackout if you ever decide to go that route. It's a quick-attach can so with the right mounts on your rifles you can switch it easily from a .308 rifle to a .223 (those rifles almost always have different thread patterns, so using a direct-thread can would require an adapter on the .223 rifle).
