We are at the point now that you just cannot count on buying your favorite powder. There is nothing quite like finding a couple pounds of rifle powder that you are not familiar with at the LGS. I have tucked a powder bottle under my arm while I checked the powder online, but it would be nice to have a list of acceptable .223/5.56 powders for use in an AR.
These are the ones I know and use:
W 748
H Varget
H 335
H 322
CFE 223
R TAC
R X-Terminator
P.S. It is understood that not every powder is ideal when common bullet weights for the 223 span 50 - 77 grains.
Running Varget in main stream .223 loads is nuts. It would be smarter to trade it for double the amount of another powder. People are crazy enough to take that action too.
Im pretty green to loading for an AR but I’ve had good luck with IMR 3031. 22.4 grains grouped nicely under a 55gr FMJ at 50 yards in my Mk12. I was trying to develop a blaster/training load (not super focused on accuracy, but cheap and consistent) so I could throw it on the Dillon and crank a bunch out. I’ve put that on hold now, I can’t find any more 3031, and I was caught with my pants down rifle primer wise. I normally just load pistol in bulk. I’m going to focus on precision 77gr loads for the Mk12 now.
Like everything else,hard to find but 2230 was always my go to powder,2520 also worked great. I used this for blamo/3-gun/plinking ammo. I was never a precision AR guy !
I have been rocking on buying powder. Up to 30lbs of powder the last couple of weeks. Buy it while you can. Got 3lbs of Winchester 748 a couple hours ago at Midsouth.
Have heard a few guys say 4198 is ‘ok’ for the lighter bullets so I tried it one time and hated it.
Stuff has got to be the least ‘easy’ AR powder I have ever messed with and was just not worth my efforts.
Fortunately I will have to burn up a hundred lbs of ‘good’ AR powders and everything elsewhere will still have to be sold out before I ever get close to considering fooling with that crap again. If I had a bolt action in .223 I would be using it up and getting it gone but for AR use - Hell no. Not for me…
AA2015, AA2230, IMR3031, AA2460, H335 and Benchmark for 55 and 60 grain bullets. If you are shooting heavier bullets then IMR4895 and IMR4064 up to CFE223 AND AA2520.
