Why take the chance? Just get a Bartlein, Brux, or Krieger and be done with it. When those barrels have the reputation they do, and used by the top shooters in the world, that should tell you everything you need to know.
This ^^^ ( You could probably, Add, Shilen & Rock Creek to, this List )
And, If wanting a very slightly "Second Tier" Barrel, you could add, a Criterion, "Rem-Age Style" Barrel that, You can install yourself with, Minimum Tool's and a Headspace Gauge. ( saves G-S fitting / Chambering, costs )
With "Tuned Loads" you can get into, the LOW 2's and 3's,. If, installed and rifle is, Bedded, correctly, etc.
They ARE, a Great replaceable Barrel that, is good for, Varmints, Big Game Hunting and Steel Plate Fun,. IMO
Key IS, to Match Bullets to Twist / Velocity and KNOW How to,.. "Tune" Loads ! ( For, Sub 1/2 MOA Accuracy )
Probably WON'T Win, a BR Match, tho
