[Last Edit: jaqufrost]
Since I got the last thread locked, I thought I would restart a new thread with the load data others have used from that thread and any other data I come across.  As Dryflash reminded us in the last thread, this is not a "where to find thread" so please don't post links on where to find components.

The Data:
Klienman reports 2800FPS with 26.5gr of CFE223, CCI#400 primers and a 16" barrel. OAL=2.25. - no pressure signs.
Klienman reports 2870FPS with 27.0gr of CFE223, CCI#400 primers and a 16" barrel. OAL=2.25. - no pressure signs.
CTRob65 reports 2832FPS with 25.9gr of TAC, CCI #41 primers and a 16" barrel. OAL=2.26. - no pressure signs.
CTRob65 reports 2897FPS with 27.2gr of CFE223, CCI #41 primers and a 16" barrel. OAL=2.25. - ejector swipes and some primer flattening.
Stump70 reports 2800FPS with 24.0gr of 8208 XBR, unk primer, unk barrel, unk length. - ejector swipes
RCC1 reports 2892FPS with 26.5gr CFE223, CCI#400 primers and a 16" barrel (suppressed). OAL=2.26.
RCC1 reports 2945FPS with 27.0gr CFE223, CCI#400 primers and a 16" barrel (suppressed). OAL=2.26.
RCC1 reports 2982FPS with 27.5gr CFE223, CCI#400 primers and a 16" barrel (suppressed). OAL=2.26.
RCC1 reports 2771FPS with 24.0gr 8208 XBR, CCI#400 primers and a 16" barrel (suppressed). OAL=2.26.
RCC1 reports 2810FPS with 24.5gr 8208 XBR, CCI#400 primers and a 16" barrel (suppressed). OAL=2.26.
RCC1 reports 2846FPS with 25.0gr 8208 XBR, CCI#400 primers and a 16" barrel (suppressed). OAL=2.26.

If you have a load your using for M855A1, post it up and I'll add it above.

I hope it does, I just got a new supply of these and am more comfortable experimenting some more. If it warms up a bit I will run some new loads and let you all know how it went.
I would also like to hear some of your guys experiences.

I'm just dying to buy a 100 of these for some reason.

I just can't justify it in my mind. I think it would be kinda cool to have some, but load work up would use up 25% of them I'd think.

Wound channel on YouTube used a chronograph with a 16 inch barrel and got a velocity of 2982 from factory m885a1.

Another video from jwg223 showed a dissected charge weight of 25.7 of smp-42 (or whatever the new powder is called).

Im wondering what primers were used by Kleinman, Nato primers are hotter.  What OAL was also used?

I believe the factory load is 25.5 to 25.7gr of SMP-42. Unfortunately that powder isn't available to us. .mil tests each batch of powder and adjusts the load slightly for each batch.

 I'll try and check a few of my factory loads for overall length. Personally I'll probably adjust out from factory if there is any room left in my magazines.

Seems we could maybe use Barnes TTSX Lold Data for 16.5" barrels as a guide? I might pick up a lb of CFE223 for these... are you all using #41 primers? I'm thinking of loading mine in match prepped LC brass with SB Primers. Will seal the bullet and primers too.

TAC might actually be a better powder for these...

I tried some out a few days back, but the results weren't promising.
26.1gr TAC
Rem 7 1/2 primers
2.250"
no crimp

Three rounds grouped 1 1/8" at 50 yards from a 1:7 PSA Premium upper that will cloverleaf 64gr Fusion and IMI M193 at 50yds.

No chrono data, but the recoil felt the same as IMI M193 and the ejection was the same also. POI was about 2" lower than the Fusion and IMI.

Also loaded was 25.5gr, 25.8gr, 26.4gr (1 1/2" group) and 26.7gr. I did not try the Barnes TTSX listed max charge of 27gr, but there were no pressure indicators so I might try going a little higher.

I have some loaded with Varget and CCI #41 primers and will post the info if results are good.

I also just received some CFE223 and might try this with CCI if the Varget doesn't show any promise.

[Last Edit: CTRob65] [#26]
Quick update from my last two outings ...

firearm: PSA Premium upper receiver 1:7 mid-length 16" barrel with MBT and variable power Primary Arms scope.

On the 17th I tried the M855A1s with Varget. I loaded 3 rounds each of 25.8gr, 26.1gr and 26.4gr with CCI #41 and a coal of 2.255. Once fired LC '10 brass trimmed to 1.752". Crimped with Lee FCD.

The best of those were 26.1gr which yielded a "group" of 3/4" at 50yds. The "group" was two inches lower than factory IMI M193, 64gr Fusions loaded with BLC-2 and 62gr Fusions loaded with H335.

The other loads were ridiculous. There was no high pressure signs, but that wasn't surprising since the max charge is considerably more. I have never worked with compressed loads before and I wanted to try these projectiles with CFE223 before compressing the Varget too much.

I do not have chrono data for the Varget.

Today I tried some loaded with CFE223. Three projectiles were each loaded with 26.2gr, 26.5gr, 26.8gr and 27.0gr with CCI #41 and a coal of 2.250. Once fired LC '10 brass trimmed to 1.752". Crimped with Lee FCD.

The best "group" was with 26.5gr. It was a hair over 1/4", but it was also 2" lower than the previously described zero and 1" left.

The second best "group" was with 27.0gr. That one was about 1/2" ... still two inches low, but no windage correction needed.

26.2 and 26.8 were again ridiculous at around 3". No pressure signs whatsoever.

I have since loaded up another round of 26.5gr for my next trip in which i will have my chronograph. I'll see if my velocities match Kleinman's.

Updates to follow ...

I'd expect wider spacing on the nodes than 1 gr of CFE 223. Really need chrono data to see how much more speed that .9 gr got you.

No pressure signs with 27gr CFE. Interesting, I still haven't got to try mine yet. I may venture out tomorrow it it isn't raining.
My next range trip will be busy so I want it to be nice out so I can bring the chrono.
I will be testing the above loads for M855A1 as well as the same loads with CCI 5.56 primers.
I want to "unload" my muzzleloader and make sure my zero was still on after being banged around all season. (Didn't shoot anything)
I also need to test some Barnes TTSX 55gr with H335 I have loaded up.

The sources were the Barnes link PointBlank82 shared above, Lyman 4th edition, Lee 2nd edition and Hornady 8th addition.

The only references that came close to the style/weight of this projectile was Barnes and Lyman. The Lee did have 63gr jacketed listed, but the Hornady only had 60gr projectiles listed.

I took advantage of the last day I'll be able to shoot for a while and finished off the CFE223 run. I was not happy with the results whatsoever and will move onto another powder next go around.

The best grouping I had out of my PSA/FN CHF barrel was 2moa. I'm hoping someone else wll chime in on group sizes.

The lastest chronograph data from the CE Digital. 42 degrees today and not as foggy as yesterday.

There was some primer flattening (more that the typical) along with some swipes on the 27.2gr. I will not be going any higher with CFE223.

Both groups opened up to the point of being laughable.

The importance of more than 3 shot groups ...

3 rounds of 26.5gr CFE223 vs a 10 round 1" group with the only difference being about 20rds through the barrel between days.

I knew I was going to bring the chronograph with me today so I said screw it and I loaded up some more projectiles with Tac and CCI #41 primers. For no good reason other than curiosity I changed the coal from 2.250" to 2.260". It did not make any difference in group sizes.

Hmmm, maybe take it up to 27 gr of TAC?  Nice SD on the 25.9 gr...
Link Posted: 1/24/2017 10:50:02 AM EDT
[#37]
Cfe223 is starting to look like a poor choice for these pills.  After looking through all this data, and especially CTRob65' run with TAC, my theory is that SMP-842 (or whatever is used) has a burn rate closser to 748.  Maybe its 748 without the copper fouling chemical.

CTRob65 used 25.8 and the velocity was not close to the factory 2900 from a 16 " barrel.

Lyman shows 63 sierra smp with 27.5 as max load going at 3147 with a 20" barrel.

If anyone can find out the burn rate of smp842 it would help out.

Dont get me wrong cfe223 is not useless, I can get 1/4 MOA with the old m885 pills at 200 yards with a green mountain 20" 1/8 twist  with 26.5 2.260 avg of 2950fps and a cheap  NCstar mark3 3-9x42 (dont knock it until you try it).

Bringing this back up to see if anyone has had more experience with these.

I recently learned that the M855A1 is a 3moa round and minimum velocity for a level III plate is around 2100fps.

It should be more accurate than 3moa depending on the gun. Early loading were better on Armour. The penetration on vests has more to do with plate type. Some materials shatter the steel tip better than others.

M855 is usually 3 MOA. The .mil standard for precision is 4 MOA or less, correct?

I read that M855A1 was about 1-1.5 MOA from an AMU rifle. Could have been a select lot I suppose.

I've had good results with cfe223 in heavier bullets.

It does not seem to do well in lighter bullets and this thread is confirming that conclusion.

Thanks for this thread and work OP.

I mean to say do well as in strictly velocity, not accuracy.

@Kleinman Just to verify, CCI#400 with all your loads and no velocity data for 27.0gr of CFE?

that XBR gets real tight on the charge weights with heavier bullets, I
started at a conservative 23 grains and 23.5.

PMC 1x brass trimmed to 1.750. CCI #41 primer. Bullet seated to 2.245.

23 grains:

2712
2662
2694
2665
2675

23.5 grains:

2751
2711
2772
2765
2718

No signs on the brass that indicates anything. Thought I felt/heard a slight crunch
on the 23.5, so going up from that will more than likely be a compressed load.
Accuracy was not bad, but it was from a 16" CL with Acog. Not the ideal paper puncher.

Do believe there is a little more leeway for the XBR, but not much, so watch out.
