I bought 2 Shaw barrels on a group buy several months ago. Both 26" varmint contour stainless in 7mm-08 and 6.5 Creedmoor.
The 7mm-08 barrel came first,and it took a while to find what it liked to shoot.It prefers 150gr-160gr bullets,and will shoot them in the .500" range,while others weights shoot in the .750"-1.0" range.
I just built the 6.5 Creedmoor today,and haven't shot it yet.
I prefer to buy McGowen,Hart,or Pac-Nor barrels,but I couldn't pass up buying these Shaw barrels for $158 each.
