between H335 and CFE 223 ?

rebs · July 10, 2013, 06:01 AM

Has anyone used both these powders and found one to produce better accuracy with 55 gr bullets in an AR 223 with 16 or 20" barrel ?

I've used both, in both cases accuracy variances were negligible. Small enough to blame on the guy behind the trigger. I prefer H335 though, mainly because I run it in multiple platforms.

I've had better results with cfe223 with light bullets in my 1:9 twist AR. I use both powders.

Thank you for the replies

I have tested both and continue to use both, depending on availability. Here are my conclusions:

- Both H335 and CFE223 are very accurate, I can't notice any difference within my abilities.

-CFE223 requires a slightly higher charge (~1gr) than H335 to achieve the same muzzle velocities. This means that I get around 10 less loads per pound of powder with CFE223.

-H335 and CFE223 preform better with magnum primers.

-CFE223 does work for controlling copper fouling!

are cci # 41 magnum primers ?

I'm not sure that they're magnums, but I do know they have thicker primer cup material. Somewhere around here it was just discussed that they are thicker to prevent any chance of Slamfires in a free float firing pin setup ( AR, etc)

I was told at the gun shop that the 41 primers are just a thicker cup, to be used with AR type rifles. AR-15's commonly have a free floating firing pin, which means it taps the primer when loading. My friend has an AR-10 which is the .308 version and his has a spring around the firing pin. You can safely load with the CCI 400's, but the 41's are recommended. I've used both primers with the same charges/bullets and had equal results.

Not sure if you noticed, but the 41 primers became unavailable before the 400's. the shop told me that the factory was not shipping the 41's, because those were being used for military ammo at the time.

I have used all CCI #400 and never had a problem, I tried the CCI bench rest primers and the CCI #41 and didn't see any difference in any of them.

Why is the H335 and CFE223 powders better with magnum primers ? I am curious as I haven't tried any magnum, primers for my 5.56 or 223 loads

Spherical powders need that extra shot from the magnum for reliable ignition, at least that's the theory. I've always used 400's in all my guns, including with my ARs and have never had a problem either.

I do notice the 41's don't flatten as much as the 400's though, a resultant of the thicker primer cup.

Here is a velocity test I did comparing CCI 400's and CCI 450's using CFE223 propellant. I have posted this before, but it does answer the above question. Higher velocities indicate better ignition of the ball powder.
