I had originally started the discussion on subsonic selections for my rifle here PWS MK111 + 7.62x39 Subs
I ended up getting about 220 rounds of 196gr Brown Bear subsonic (FMJ).
RIFLE SETUP
PWS MK111 Mod 2 (7.62x39)
Vortex PST Gen II 1-6 (MOA)
PWS lower w/ PWS standard buffer, buffer spring, tube
Q Thunderchicken
I tested the subs with 10, 20 and 30 round c products mags and they ran without any malfunctions on gas setting one (Which would be the "unsuppressed" setting). 100 rounds total probably.
Context: Normal ammo like PPU 123gr sp, Wolf and WPA are on gas setting 2.
Really hot ammo like Tulammo 8M3 on setting 3.
(^all suppressed^)
CHRONOGRAPH
I chronographed the ammo as well just for fun w/ my Magnetospeed.
They all averaged 1010fps from the 11.85" barrel + Thunderchicken, with some of the slower ones around 980fps, and fastest at 1045fps
SD 25/ ES 85.
ACCURACY & BALLISTICS
wasn’t terrible, they grouped right around 2” at all ranges, which is fine for their application (head shots on varmints and pigs), and I'd say better accuracy in this rifle than many other subsonic selections. For context, I get right around 1 MOA with the supersonic 123gr PPU sp.
W/ Vortex PST Gen II 1-6 (MOA) it was an UP 18 MOA adjustment up (or 5.2 mil) to a 100yards zero.
*I’m usually running 123gr PPU soft points, which the rifle is zeroed for.*
I did attach the drop chart with my zero for supersonic, and drop chart as if I zeroed the rifle for these subs (in MIL since most of you use MIL)

I’m super pumped! I’m going to have to order a case now haha.
