I don't know much about he 22-250 compared to my experience with the other 2. I have both a .243 and several 6.5 X 55's.

I'd give you the nod for the Swede. Your 22-250 will throw pills up to 80 grains, the 243 throws stuff from 70-115, and the Swede load pills from 85 grains to 160. Not all bullet weights will do favorably in just any barrel/twist. And of course I might have the same barrel as you and get different results. Guns can be particular.

Your 22-250 may like a certain weight bullet and a 243 and Swede likely will too ... depends on your twists ... but the 243 has a smaller window of bullet weights it'll handle well ... 55 grains to 115 and likely it'll do best in the 70-100 gr realm.

By comparison a Swede will be able to throw bullets from 85 grains to 160 with the sweet spot being in the 120 - 160 grain realm.

I'd opt for the Swede to give you a better spread of bullet weights and applications.
