300blk, 220 smk, which powder???

For 300 blk, w/ 220 smk’s, what’s the best powder for this load?? H110??

I have had good luck with H110 and AA1680. Hodgdon and Accurate both have the data on their website.

I use N110 with 220 grain SMK’s. It is a super clean load and pretty accurate too.

AA1680 works best for me in a gas gun. H110 is really dirty but works fine also.

N-110 is good, but expensive. I use it with Berger 230s in my bolt gun.

To me Lil’gun was quiter and cycling supers and subs with no problem

AA1680 was the best choice for cycling a AR, subsonic. for supers, H110 works quite well

AA1680 has been my go-to for the subs. Tried CFE BLK. It works, but I had less accurate subsonic groups in a 16” barreled AR than with the 1680.

Ok. So to be specific, if I wanted super accurate, subsonic 220gr out of 12.5” barrel gas gun. Which one is the consensus? Accuracy first, burning clean is second to accuracy. I am not suppressed yet, but will be at some point soon. But even without, the gun shoots Remington umc 220gr of the shelf very accurately. So I am trying to replicate in a hand load

Give lil’gun a try.
It is extremely accurate out of my bolt gun.
My AR I have not tested it for accuracy.

If anyone here will be at Berger’s, I’ve got 2 lbs of 1680 I’ll pass along for 25 each.
