Finally got around to running some subsonic 308 ammo over my chrono. I cut back one of my AR-PSR 308 barrels down to about 18 inches and I put my Thunderbeast can on the end.
A spoonful of Trailboss under a Sierra 175 goes about 1070fps and is incredibly quiet. Low ES/SD and accurate. Very happy with the combo.
Now I have something to do with all those 175 pulls I bought.
I did this with a 208 AMAX. 11gr TrailBoss kept it nice and quiet. We hit a couple hogs at ~245-ish yards with it. Dialed up so much I thought we mortared them piggies.
Just doing what I can to stay on this side of the dirt.
