Here's a 300 RUM that Nate built for me last year. I took it on its maiden voyage this past fall to WY and shot a nice whitetail. Finally had time to post. Specs: Borden Timberline single shot action w/SSG bolt knob Lilja 30" 10 Twist #7 contour barrel SSG muzzle break Jewell trigger Manner's T2 stock -desert sand color NF Rings Ken Farrell 20 MOA base NF 5.5-22X56 w/npr2 reticule K-G Kote barreled action dark earth tan with foliage green bolt handle and rings B-square anti cant Badger cosine indicator Sinclair Tactical/Varmint bipod Here is a look at what she'll do. This gun will shoot some small groups. I just happened to find this one for this post. Notice this one is from a clean barrel, the gun will average .3-.4 with ease. WY whitetail taken at just over 450 yards.
