A buddy gave me an unopened 2 pounds of CFE. Going to shoot Hornady 55 grain FMJ-BT W/C in my AR 15 with 20 inch barrel with 1X8 twist. The manuals seem to be scattered but agree that more powder is necessary than with the H 335 which I have been using. Hornady manual on page 166 says 24.8 to max 27.4 with an OAL of 2.200. Probably from a 24 inch "machine." I needed much more H335 powder than the manual indicates that they used. In fact their max was about my functioning load. And not hot at all.
Will start my ladder at 24.7 and go from there.
Where did you guys wind up? Other thoughts?
