I reload HS6 behind 147 grain Berry's plated FMJ. Decent shooter, no louder than factory.In the hunt for quietest 9mm sub sonic load I want to test some HS6. I was wonder if anybody has experience with this or even 147gr bullets?
I have a load with N320 but I feel it could be quieter
I am open to other suggestions for powder but want to use up what I already have
