How difficult is it to open a 222 Rem bolt face to accept a 22-250? The difference in heads is 0.1 inches. I have a Remington 700BDL in 222 Rem, which I shoot very little. I've never reloaded for, nor played with, a 22-250. ER Shaw can build a 22-250 bbl with a 1:9 twist, which should stabilize bullets up to (and maybe exceeding) 70 grains. So, I am wondering about re-barreling it to the stronger cartridge. Alternatively, I could sell the triple deuce and buy a 22-250, but I'd still have to rebarrel it to get a faster twist. Any thoughts?
