For everything you’ve described, once it’s put together and ready to go, I’d run the 180 or the 166 grain Hammer Hunters and call it a day. It’s hard to beat the the performance in accuracy from 0 to 600 yards.Ok guys I need some help, I want to build a rifle for long range Elk hunting next year in Montana. I have enough points I SHOULD get one. What I want to do is build a rifle for long range elk hunting between 300-600 yards. I was thinking about building it off of a Weatherby Vanguard in 300 Weatherby then replacing the barrel, stock, trigger, and whatever else you guys might suggest. I am in the dark on this a little, so any help would be nice. Another thing is I don't want to go with some ridiculously heavy barrel. Honestly, I was thiking about a Shilen #2 contour barrel. I would like to keep the rifle at less than $1200 plus optic. The scope I am thinking about is the Vortex Viper PST 4-16x50.
