Ya you can hear the difference in gas-letoff out the Can on the bolt-gun for sure. It is quieter with the fast burner n-320 shot side-by-side with the A#9 & suppressor.
I got to admit, I am pretty wary of playing with even faster burner's. I know enough to know, " volatility " .
Clean is on the money too. You see it in the empty cases too. Hot, Fast & clean on the burn. The guy who talked me into using the n-320 uses it for the heavy 147's in 9mm semi-auto 'pistol' platform with suppressor. He swears by it.
.
edit to add:
Load example for reference . using 180 grn bullet weight out a, 16" barrel - 8 twist 5r cut. with an even 6.0 grns n-320 was average 940 fps vel.
