Some of the guys that went with the 1 in 7 twist in there 223 are going back to the 1 in 8 for best accuracy. some even tried the 1 in 6 and as far as I know they did not work at all.
The 22/250 is a much faster more powerful cartridge and you can over rotate bullets and destroy
there jackets if to much twist is used.
