Proof Research 6.5mm 22" Sendero Carbon Fiber Barrel Blank

This Proof Research blank is a 22" Sendero contour .264 barrel with a fast 1:7.5 twist, a good match for the long, heavy 6.5mm bullets used in long range work. It is sold unchambered: a gunsmith fits it to your bolt action and cuts the chamber and threads. The breech section is 2.5" with a 1.20" shank diameter.

The carbon fiber wrap is up to 64% lighter than a steel barrel of similar contour and sheds heat better.
