I'm shooting CFE 223 in a 22-250 using 50gr bullets (vmax, , zmax,varmint extreme, etc.) Really love this powder in the 250. It shoots with excellent accuracy and is fast. 37gr is giving me 3,900 fps with a 26" 1x14. Haven't even tried to go past the minimum loading recommendation. Gives good ES and cleans up easily after a lot of shooting.
CFE223 worked well in my two 22-250's as well... AR Comp is maybe even slightly better.
