My rifle is a Savage 112BVSS.
Factory Barrel, 26" 1:10, factory heavy contour.
Recoil lug from sharpshooters supply.
Trigger work done by Chris V. At h and H gunrange in OKC.
There are a few modifications to my stock, for position shooting.
I use a Millet 6-25X56, 30mm tube with mildot. It is mated to my rifle with millet angle lock rings, and a Ken Farrell 20 MOA base. With this setup I have shot beyond 1600yds.

As mentioned in this thread, this group, and most I shoot at this distance is shot from a harris bipod.
