To simplify the 22CM/22-250 comparison you could boil it down to three facts; 1) to shoot longer (heavier) bullets you need a faster twist 2) more speed requires more powder. The 22CM has more capacity that the 222-250 and the 220 Swift. And you don’t have to fire-form brass. 3) to shoot the 22CM you should be a hand loader. You can buy loaded ammo but is hard to find and will likely need to be mail ordered.
I am a handloader and I have both. I prefer the 22CM for hunting most of the time. I shoot the Sierra 77gr Tipped Match King and have talked hogs out to 500 yards. I also shoot the 22-250 with 55gr Sierra Blitz Kings. It doesn’t miss. I would probably limit my shots with the 22-250 to about 300 yds For head and neck shots. I would never attempt a shoulder shot past 200 yards unless I was shooting a monolithic.
All that said… I also have a Tikka 22-250 with a 1:8 twist shooting the 77 gr TMK’s that I would shoot out to 500 yards because it is shooting a high bc bullet.
All my rifles will shoot under 0.4”. It is hard to do that with store bought ammo. I typically start .020” of the lands and test powders until I get a good group near the max load. Then I vary the seating length in .003” increments, reducing to CTBO until I find a node. I started doing that this year and every rifle so fare has become a one holler.
When you shot them in the head or neck the bullet’s penetration and terminal ballistics are not as important.
