ParticipantAnyone use N330 on their 147gr loads? What are you loading? Gun, barrel length, etc. would be apprciated as well. I’m starting at 3.8 gr but have a feeling I’ll settle around 4.1gr out of my 4.6″ barrel Atlas Athena.

ParticipantFor subsonic I wanted a 100% burn and subsonic velocity for a suppressor using the RMR 147gr Flat Nose bullet. I chose VV N320 for that. 3.5gr and COAL at 1.110 inches. In a Sig P226, 4.4 inch barrel the unsuppressed velocity was 902 fps, measured by Labradar. It shoots well. QuickLoad predicts or calculates 100% burn and 951 fps.
VV N330 takes more powder and yields a little higher velocity but still burns 100% according to QuickLoad. 4.1 would be a pretty hot load but still quite doable from the looks of it.
I guess it depends on what you want to do.
