What bullet was it chambered for by GAP in addition can you also provide a couple of pictures concerning groups shot from the rifle.
Currently acquiring parts for a 7 saum with nothing left needed but the stock. At this point I would be better off selling my parts as your rig would certainly speed up the process but only if it was tricked for the 180s.
Seeing as how its a 1in8 it likely is. I don't think the SAUM has enough gas to make a 180 fly as it should. A 168 Berger is all you need. Oh, and NICE RIFLE!
. Nice snag on this beauty. I think you saved about $700 and 8 months of waiting.
