what kind of MV's are you getting out of that 12.5-inch barrel?
my 12.5 is in build now and should have it up and running in a couple of weeks hopefully. have two brands/types of ammo to test and will provide MV data when i get it back in-service. will be running a Gemtec HVT 308 suppressor on mine.
