I have two of them, one is a 24" in 338 win mag on a M77 and the other is a 26" in 7stw on a trued 700 action. Both have a Vais break. The light weight is great for Az. hunting and both shoot just fine. The furthest I have shot the 338 is 200yards and it will keep MOA. The 7stw barrel was a learning experience for me.... I did not specify the twist rate and they did not ask. I ended up with a 1 in 11 twist which shoots the 140gr Interbonds awesome, but not so good on the heavier bullets. One thing I will say, if you get a barrel in a magnum round make sure you get it with the brake! Their barrels are lighter and you can feel the difference in recoil.
