22.250s have been working fine for me for a long time...
only reason I see for me to built a 220 Swift is strictly curosity... but if it never happens I don't think I'd be missing much...
a 243 necked down to 22 caliber makes more sense to me than a 220 Swift... which brass availability sucks right now anyway...
^^^^^ This ^^^^^
I would do a 22-243 Middlestead before doing a 220 Swift, but based on my very limited experience with the 22-243 and 22-6mm, I would probably do a 22-250 AI if barrel life was important.
