Powder for 6.5 Grendel (120gr out of AR platform)

[Donkin]

What’s the best powder to use? Anybody care to share their data. Specifically out of an AR platform. Was going to use RL15 or H335, but read somewhere that those powders are not ideal for a gas gun?

I just began loading for my SLR 6.5G with the 123gr Hornady SST, I have used CFE223, Winchester 748 & Alliant AR Comp so far. AR Comp is standing out for accuracy in my rifle (19.6" Odin 1:8t)

I've been using Benchmark and it has worked very well out of my Odin Works barrel.

Thanks for the reply, where did you get the load data from using CFE223, I can’t seem to find it anywhere in the literature I have on hand, besides what’s on various forums.

Will give that a try, thanks

I've been using 8208XBR and AR COMP with 120gr smk's, 123gr Lapua Scenars and 123gr SST's. 8208 and AR Comp are both extruded and should be less temperature sensitive than CFE223 (Ball powder)...CFE223 seems to be the velocity champion in Grendel though. Fwiw, Nosler load data claims 8202 as the most accurate powder with their projectiles... but the downside is once you start approaching max load on 120gr+ projectiles you start running out of case capacity with 8202\AR Comp...28.0gr of 8202 and 123gr Scenars feels like a compressed load

Hornady's latest manual has CFE223 data
