Been working on gathering parts for this for a while. 10.5" Southern Ballistics Research barrel 338 Spectre barrel and bolt on a SBR'd FN receiver. Matching form 1'd mostly Titanium can with double clipped cerberus baffles. Picked up a thousand rounds just as the ammo supply dried up . Got her all together today and test fired a 300 grain sub in my garage because thats a thing. I have a 12" diameter pine log in my garage I use for test firing. Yeah, in one side and other the other and went thud on the brick wall behind the log.
