Rank the subsonic powders for me

Post by Blackout! » Sun Dec 27, 2020 2:22 pm

I have the following powders and want to tap the vast knowledge base of the community on these for subsonic 190’s to 240’s

IMR 4227
Accurate 5744
RL 7

If I remember, the 5744 was very dirty, Un-burnt powder on the bench and in the action. Maybe chg was too low? Didn’t chrono that load

I have been using H110 on 240 gr SMKs in a Remington Mod 7 with an Omega can. It’s been great. Very accurate. Quiet as a church fart too.

I have loaded a ton of 190’s using 4227. Once again, super results out of a 10.5” Noveske with a Saker and out of the bolt gun too. Accurate and quiet as can be expected in an AR.

The 4198 ... I guess I bought this in the great powder shortage of 2012? Where does it shine? After I run out of 4227 and H110?
