I've got a bunch of it and 1680 arriving Monday. Any particular recipe you found that your 16" barrel favors that you would like to share?CFE BLK has been the fastest and most accurate powder I've tried in my x39. I've tried several and CFE BLK beats them all. More than 2400fps in a 16" barrel with a 123 is fairly impressive to me
Cool--thanks for that. I'm about to make a post on shooting budget stuff--you might find it entertaining.Stag my X39 upper likes 28.8 grains of CFE BLK with any .310 123 grain bullet I've tried. Over 2400fps easy on brass and accurate. I can't complain
