It's a 12BVSS .308 with the AccuTrigger and apparently the even newer Phoenix magazine system. Sitting on top is a Ken Farrell 20MOA base, Burris Signature Zee Rings, and a Bushnell Elite 3200 5-15x40mm.
Excuse the crappy groups, I'm not too experienced in distance shooting. I hope to understand better someday. All I know is the rifle seems to be more capable than I.
Oh yeah, it was shooting 175gr XM118LR at ~2580fps and was supported by a Harris bipod and a sandbag at the rear. 109 yards, wind only noticeable by the kicked up dust blowing left one minute, right another minute. Don't even ask me about temperature, elevation, slope, barometric pressure, or whether the tide was coming in or going out
