I own a custom 338 rum that weighs right at 9.75 with a #4 contour barrel, the Vortex AMG in Hawkins 25 MOA hybrid long range rings in a McMillan Game Scout Edge stock... It's as light as I would ever want a 338. Next barrel might be a #5.
Thats the exact same thing Travis is doing for me....and the same optic I was thinking about for it.
Ask Travis about his #5TS contour if you haven't already started. Its supposed to be a good cross between a 4 and 5.
Also how do you like that AMG? I'm considering it in place of a NXS.
I figure all said and done, rifle, scope, loaded, slung it'll weigh between 11-12 pounds
