We use Broughton 5C. I really like the guys at Bartlein as well, but my guys that break in our rifles and shoot accuracy groups believe that the buttoned Broughton comes into its own faster.
We usually have about 75 rounds through the gun before it goes out. If we have to put another 30 rounds into a barrel, it costs $$. So the extra cost of the Broughton is a wash for us.
The countour is right in the 4.1 to 5 contour. We finish .670 at the muzzle (25.5 inches) with about an inch of shank infront of the recoil lug.
