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.
Yup. And it is a 40 S&W that is accurate enough to hit an orange at 300 yards that you can not hear if you are more than 20-30 yards away. Or I can load the same bullet up to 2700 fps. Not many 40s will hold together at that velocity.
You know I like my coffee sweet in the morning
and I'm crazy about my tea at night
