What's the go to quietest and cleanest powder to shoot subsonic 9mm 147gr?
Only shooting suppressed pistols with it and suppressed M11/9 smg and currently have RMR 147gr FP plated bullets as well as Berrys 147 FP's.
I have been doing a bunch of post digging and see people a few years back were really ecstatic about the Vihtavuori N320 powder with the 147gr, as well as the N330 and N340 powders. People were saying it was the closest to the "Special K" ammo.
I have the latest 50th Lyman and 10th Hornady books and there is only one mention of the Vihtavuori using the N340 powder with TMJ 147 9mm, 3.9gr @ 947fps.
Is there newer powders out now that are superior to the Vihtavuori for my intended use? Can anybody recommend any recipes with this powder or one they use themselves? I just want something comparative or better than the Federal American Eagle 147gr I currently shoot as well as cleaner because shooting with a can throws everything back into the host.
