To start, I have never owned a carbon barrel. What is the smallest contour carbon barrel on the market, and who makes it? Wanting to build a lightweight/long range setup with my 7-08 Rem 700. This is my rifle of choice for deer. I'd like to keep it as low profile as possible, lightweight and hopefully increase accuracy. Wanting to stick with a sporter or magnum contour. Is this possible with carbon barrels?
