Loaded some 105 MKZ's with CFE BLK and tested them today in my 16" ARP Scout 5R.

-Federal brass
-450 primer
-28 gr CFE BLK
-2.285 OAL
-105 MKZ
-Light crimp w/FCD

Average speed was 2777 fps, and they cut one ragged hole at 100 yards. This powder as lots of potential in the 6.8. Once I got over SAAMI loads, CFE BLK really turned it on, with no swipes or flattened primers.

Ive also had excellent results in 7.62x39 with CFE BLK, and plan on experimenting further. It's easy to find in my area, and I'm definitely happy with its performance.

The numbers look impressive from a 16 inch barrel, I have a couple boxes of 105's I haven't yet started working on. I'll have to keep an eye out for CFE BLK in the local shops. Thanks for posting!!

Crayj was the first to post his loads with CFE BLK, and I followed up. Haven't heard of much experimentation with CFE BLK, and don't know why.

I'm guessing this is faster burning powder than AA-2200? wondering what it can or will do with even shorter barrels ??
I believe it is faster than 2200, but I can't get the same speed from 2200. The only thing that I don't like about it is that it makes my Lee powder dispenser drag. BLK is a very thin flake type powder, and it makes the charges vary a bit. I've been using my trickler to make sure the charges stay the same.

i've got 800 X39 cases primed and ready to load up, been following your testing, talked with H about translating CUP to PSI, think i'm going to slowly work into the 31gr area and see what happens.

have a metric ton LOL of 6.8 bullets to load, have about 500 cases ready to load, i'll be following this thread. thanks 303

Do you have a direct comparison with the CFE BLK load and something else?
Same bullet, same barrel, sort of same conditions?
(I didn't search your old posts)

There seems to be some good potential with this powder.

they have a little reload data out for cfe blk and 6.8 on their website --- for a 110gr v-max they show 23.5gr @2400fps up to 26.0gr @ 2658--BUT, they pressure data shows 53400psi at 26.0 with the v-max so it could still be stretched a bit

I've seen some of the data but it would be interesting to see results comparing it to another powder using the same bullet, same barrel, same reloading techniques.
"Loaded some 105 MKZ's with CFE BLK and tested them today in my 16" ARP Scout 5R.

-Federal brass
-450 primer
-28 gr CFE BLK
-2.285 OAL
-105 MKZ
-Light crimp w/FCD

Average speed was 2777 fps"

With table data you have to put up with pressure barrels, safety factors, lab conditions, etc.
What barrel did they use? and look at the pressure/velocity for the 110gr V-max with H4198.

The 16" 5R barrel is pretty slippery.

Only other bullet I've tried with CFE BLK is the 110 HPBT. With the same recipe as the 105 MKZ I got 2740 fps. With 29gr A2200 and 110 HPBT I was getting right around 2700 fps. The CFE BLK is some great powder. 40 more fps with a grain less powder than A2200.

Cfe-blk

I ordered some CFE-BLK just now (free hazmat from Powder Valley today only).

I'm happy with AA2200 but this thread made me want to give CFE BLK a try. I'll report back when I have some loaded.

This stuff is impressive on the speed! The groups weren't the best but I'm taking full responsibility on that. I have a feeling they are better than I produced.

Hornady brass by S&B
cci#450 primer
CFE-BLK powder
105gr MKZ
2.285 coal
42*, 100y

Wilson Combat 16" Lightweight barrel and form 1 titanium suppressor

......................................................fps. ............std.............group
New 105 MKZ 27.8gr CFE-BLK..........2774..........27.6............ 1.23"
New 105 MKZ 28.1gr CFE-BLK..........2790..........35.7............. 3" (not a good rep of accuracy here, my fault)
New 105 MKZ 28.4gr CFE-BLK..........2840..........12.1............. 2" (I don't think this one is safe and wouldn't do it again)

Going to split the diff and try 28gr and adjust the COAL out just a bit.
