Ive shot several pounds of CFE223 in the 6.5 Grendel with mostly 123 grain bullets. The biggest disadvantage to CFE223 is its sensitivity to change in temperature. AR Comp is a more temp stable powder but there is limited load data available. Ive not tested my AR Comp yet but forum members report about 27 grains of AR Comp with 123 grain bullets. With CFE223 you can load about 31 grains with 123 grain bullets.
CFE223 will usually give a little higher velocity in warmer temperatures than AR Comp with same bullet. CFE223 is cheaper in my area than AR Comp. LeverEvolution powder is very similar to CFE223 and gives about the same velocity as CFE223.
