i'm going to be putting together a 300blk bolt gun, using one of the ER Shaw barrels that Gunshack is doing a group buy on....and i'm trying to determine which to buy. they have a stainless varmit contour (16.5" and .9 at muzzle) and a sporter contour made from 4140 with a .9 shoulder...

i'm going to use this gun out to 200yds...MAYBE a little farther if the opportunity arises, but i have other guns for longer range shots.

it'll mostly be shot from a bench on a bipod with rear bag....and usually shot suppressed (7.62-SDN-6). Gun will be assembled from a savage 200 in .223 and will spend its life in a hart lrt stock (afraid i MIGHT have to do some stock trimming if the fore end is longer than i expect)

which would you choose...and why?
