H322 gives me the best accuracy with 77 grain SMKs out of all the powders I have tried. Only problem, is that load is slow at 2550 fps.

Works just fine, go for it.....

Aalf, If you don't mind my asking, what's your load with the 55gr NBT's?

I'd rather not say, 1st due to me shooting moly plated bullets, and 2nd my lot of powder dates back from a long time ago, and is not like the current extreme version.


Fair enough.

I gave up on moly some time ago, and I'm also using the new extreme version of the powder.

Thanks for sharing your experience.

I normally load it with 25 grains in the 223....if I want a little more zip, I'll bounce that up to 26.5 grains...

Never had pressure issues, popped primers etc...even with the 26.5 grain load..

I use Small Rifle Primers... no magnum, don't see the needs..

I also use a lot of Benchmark, and AA2015....I use reloader 7, so never saw a need to play with RL 10... but I have burned 4 or 5 lbs of it..
I just saw better results with RL 7... I buy that in 5 pound containers... and Benchmark and 2015, I usually buy that in 8 pounders...


You are putting 25 grains of AA2015 into a .223 case and you have no pressure signs ?? I must be doing something wrong. I would live to find an 8 lbs'er in 2015. I would prefer AA2230 in an 8 pounder or AA2460 but I'd settle for AA2015.

H322 is a favorite of mine when paired with a Beartooth Bullets PileDriver jr. in my Guide gun.

I use it with 55 FMJs in a 5.56 rifle, I have a metric schidt-ton of it.

I was referring to H 322 with 25 grains and adding up to 26.5 grains when desired...

But from Steve's Reloading Pages, http://stevespages.com/224_8_50.html

it lists max charge at 26.6

OK. If we ever get powder back I'll give it a try.

H322 is my go to powder for the 223.

I've only used H322 under 40 grainers in my 223 bolters, with excellent results. The nice part is it all burns and is quieter than slower powders, I've been thinking about trying it to make a gas gun load with it, see if the pressure curve makes the gas system run better.


H 322 should be fine in 223, so work up your best (and probably stiff) load with that, then work up another with TAC. TAC seems to really like being under 50 through 60 grains.

scope adjustments can take care of that...what distances are you wanting to shoot with it...

a slower 77 grain SMK, is still flatter shooting than a faster lighter bullet in a 223...

or the other option... a fast twist 22.250... I've got one with a one in 7 twist.... she will reach out there...
