Anyone tried CFE223 for 6.8? Im looking to reduce the powders I have stocked. I currently have aa2200 for 6.8 and cfe223 for 5.56. From my reloading manual and research it seems cfe223 works well for .308 as well. Just curious how cfe223 would to in 6.8. I have 105 MKZ and 110 S&B FMJ bullets to try.

CFE223 works very well with long OAL (2.4+) and heavy bullets, not so good with lighter bullets and normal OAL, it's too slow.

I've used 32gr CFE223 under a Sierra 1830 at 2.40" and get 2600fps from my 20" Savage.

Longer than Magazine COALs

Probably not really any help, but a few folks report that LEVERevolution works better than CFE223 n 308. I suspect it does in most of the down size cartridges with heavy for caliber bullets.

Based on reports of it in the 6 ARC, I want to try it in the 6.8, TAC6, 224V and 223 with the best of the heavies for each. One of its pluses seems to be that from 40F and colder it seems to be pretty temp stable which is great for me.

Anyways just based on the 308 it's earned a permanent place in the powder cabinet. I'd like to hear if anybody has tried it in the 6.8 with 120 MKZ how it did?

Thanks I found a good burn rate chart for the various powders.

Works great in TAC6 for 85 grain to 107 grain in my experience.

Thanks Jake. Encouraging news indeed.

I would be wary of Leverevolution in 6.8 based on the burn rate chart. I guess if you had a longer barrel. If I recall correctly a slower powder id better for a heavier bullet or longer barrel and a fast powder is better for a light bullet or short barrel. I think that explains why I saw better results with Accurate #7 in my 10mm

Yep I guess I agree, heavier bullets for a slower powder. I am hoping Lever gives decent velocity and accuracy with the 120 MKZ out of a ARP 20".

The TAC6 is 22" and so is the 224V. I am hoping to be able to shoot heavies out of them too with Lever. It seems the TAC6 should be could with it. We will see.

I think CFE223 is just a tad faster than Lever. The big thing is pressure and keeping it in the safe range then getting a velocity that's accurate. Here is a different chart, I put AA2200 on it in the right spot for reference.

 

[MO14]

NO AA-22000 R-10 and H-322 are the powders I run in the 6.8mm you can cross check the burn rates to see if it comes close.

 

[earlytom]

Haven't tried H322 yet I'll get around to it though. Yes CFE223 and Lever are slower but Lever is pretty good in the 308 and CFE223 has good reports too. Some say CFE233 is dirty, but I haven't tried it yet, its on the list. Since lever is getting a permanent home as a staple in the cabinet I am going get around to trying it in the 6.8 based cartridges.

Glad to hear it works good in the TAC6 with the 90 and up to the 107.

Yes on 90 grain gold dot, poor velocity and early pressure signs.

Thanks. I might need to develop a CFE223 load then. Im using accurate 2200, but wpuld really loke to only stock 2 powders (i use accurate 7 for pistol). We went thru all the shortages and powder is next from what I read.

I can confirm that it's dirty, at least as dirty as H335. I mean, it says it's supposed to get rid of copper build up, but the black stuff is just messy.

During the last panic it was the first rifle powder I could get after 6 months, so I got 3 or 4 lbs of it. It did not impress with any of the loads I tried in 223 or 308.

As the name suggests, the powder is kind of intended for 223. It seems a rather poor fit for 6.8 loads unless you are doing something really unusual like loading 150 grain bullets through a really long barrel.

Thanks for the links. Found a lot of new data at this site. Lots of new loads in handgun and rifle calibers. Plenty of Spring/Summer testing in store.

 

[Nativeman30]

CFE seems to work well in .308. Has a nice wide accuracy node in 150 gr. Decent node at the upper end for 165. I was getting book velocities with a 16 inch barrel.

 

["Follow Me!"]

Funny I just tried CFE 223 yesturday with 90 grain gold dots. I have a but load of them but only 1/2# of R7...I've tried AA2200 and wasn't getting the velocity that I was with reloader 7. So I tried CFE 223 just see and it sucked! First I went off my speer manual and the starting load was almost to the top of the case mouth! They used Federal brass I have new Starline so that might be the problem I reduced the load to where it look normal in the case. So I did a 10 shot ladder going up in .3 grains and my staring velocity was 1900 fps and my max charge only topped out 2500 fps from a 16 inch barrel and primer was just starting to flatten. I'm holding out on my 90GD loads until I can get more Reloader 7. I'm saving my AA2200 for heavier bullets.

 

[Nativeman30]

Hmm I will see what I get when I get to that point. .308 seemed to like it yesterday. My 165 gr were matching book velocities for a 20 inch barrel (I have a 16"). I haven't tried in 6.8. I know 5.56 did not like aa2200. Thats the reason I picked up CFE in the first place. O ise Hornady's loading manual 10th edition. I have 110 and 105 pills for 6.8 to try. I don't think I have any 120s around.

47 grain CFE223 and a 168 ELD match has been killing a lot of hogs here in Texas for the last three years. Two different 308 rifles love them. They have 16" barrels and are still averaging 2728 fps. The consistent accuracy along with the terminal performance has been excellent.

Speer shows it as 150fps ahead of everything else for velocity for the 90GD. Federal Brass has less capacity than others.
