I have to stand by my initial comments listed in the link above.
Also, I had tried the 5.0 gr. AA #5 load with a 147 gr. R-P FMJ bullet long before trying the VV powders. This was a match load for me in a G17L pistol.
Way too much blowback with a lot of stinging to the face!
I stopped using them in my suppressed guns.
Any of the following should work well for you, they do in my setup using an AR platform, 5" TROS bbl. with Trident-9 attached.
Rem. 147 gr. FMJ Match grade bullet (because I have a lot on hand)
R-P primed brass (because I had a lot on hand)
1.110 +- COL
3.5 gr. VV N320 - 929.5 fps avg. 10 rds.
3.9 gr. VV N320 - 1023.7 fps avg. 10 rds. - MAX load as per VV/Lapua
A 3.2 gr. load which is only .1 gr. above min., will not function/cycle any of my guns.
I have settled on the 3.9 gr. load as my standard for use in my AR SBR as well as a handgun load that functions 100% thru my SIG 226, G17 and Walther P99 all with the Trident-9 attached. It is also very quiet.
I have found N320 to be VERY clean burning, accurate with little blowback.
N330 also works very well with the same 147 gr. bullet but with a tad more velocity.
4.3 gr. VV N330 - 1001.4 fps avg. 10 rds.
As a side note, adding a Hahn 8 oz. buffer to my AR, the 3.9 gr. N320 load seems quieter, most likely due to the bolt staying closed a millisecond longer and what little blowback there was, is gone.
