Late to the party, as usual. I picked up a pound of CFE BLK at my LGS last week since I've heard such good reviews from so many sources. I have been using AA1680 with very good results. But when I tried CFE BLK, I was quite shocked at the numbers I got from my chrony. This is from a 16 in AR 15 (.310 bore) chambered in x39 using 123 grain nosler VG, new Federal pulled brass and primers with an OAL of 2.19 inches.
28 grain, MV 2471 fps, no pressure signs
28.5 gr, MV 2576 fps, no pressure signs, best accuracy(one hole group at 50 yds.)
29 grain, MV 2643 fps, no pressure signs
29.5 gr, MV 2744 fps, flat primers
No pierced primers or ejector swipes at all with any of the loads. With once fired brass I realize that the MV will probably drop a little from new brass. YMMV
For me, this powder has added an additional 75-100 yards to my rifles effective range. Only problem is I still have ~ 10 pounds of AA 1680 left. I guess the 1680 will be for my plinking loads and the CFE BLK will be for my hunting loads. Thanks all, be safe.
