Anyone loading 223/5.56 with H 335, 55 gr bullets??

I happen to be sitting on 32 pounds of H335. I bought a case of 8pounders of it before "the crazy times" along with a case of 8 pounders of AA2230c that is very similar. The AA2230c doesn't flash nearly as bad as the H335 does. I've been loading the 25gr H335 and 55gr pills for years.
i do like the 2230c loads better for dim conditions.
I hate that I saw what would happen when BO got the Presidents office, and acted accordingly.
Both of these powders work great in 308 also.

One thing I know for sure - Wolf small rifle magnum part number NCSRM will not work well with H335

Like many others, I experience about 5-10 percent no-fires and every 4th round or so is a slow-fire (click....bang).

You should have no problems with WSR or CCI primers.

Use Wolf primers with IMR4895 and you'll be good to go.

My two .223 rifles both have 20" barrels and 1-in-9" rifling twist. One is an Armalite AR15 and the other is a Whitworth Mini-Mauser.

The AR wears a Leupold Mark AR sight with a trajectory-compensating feature. The turret is marked, "55 gr @3100 fps". Since my standard load of 25.0/H335 and 55 VMax chronographs at 3097 average, the range-compensation adjustments are very reliable.

After zeroing the rig properly, setting the turret at "4" gives dead-center hits on a steel IPSC target at 400 yards , right on the point of aim. Excellent!

I find 3100 from a 20" barrel to be a very satisfactory ball-park to play in, and both rifles shoot the same load very well indeed.

Dang, I go away and now I'm very late to this party!

Anyway, to the OP, my "standard" .223 bulk-ammo recipe is 24.5gr of H335, a CCI-450 primer and 55gr Hornady FMJBTs seated into the cannelure, between2.22-2.23" OAL if memory serves. Shoots pretty well in my Colt 6920, chronographs at 2840-fps for a 10-round average from a 16" barrel. I won't claim to have worked these up for optimum accuracy, but they will reliably hold a 10" steel plate at 200-yards from prone or sitting (and sometimes offhand! :banghead: ) Oh, and for the record I use mixed range-brass when assembling this load, which is part of the reason I don't tip the powder jug any further.

More people use H335 than any other powder for 223/5.56 and I think the majority load between 24.0 and 24.5gr
