CFE223, is a very good powder indeed, shoots great out of 2 of my 308's. In my 308 model 12FV with 150gr Accubonds it shoots 1/2" 5 shot groups @100yds, 3050fps just under max load. In my 16"bbl Ruger compact 308 it shoots 130gr hornady's 3 shots into a nickle at 100 yards @ 2900fps, max load. it is a bit of a temp sensitive powder but that is to be expected with ball powders. All in all i think its a real good powder, especially in my 16" bbl gun where i like to keep the velocity up due to short barrel. Now it's time to test out CFE223 in my 30/06
