While not my first choice in a barrel. I bought one my gunsmith had in stock when rebarreling a rifle for my fathers Christmas present 2 years ago. It is a CM #5 1-10 6mm that was chambered for 6mm rem. I shoots very well 3/4 to 1/2 with everything we've tried under 100 gr. It really likes the 75 gr Vmax. It also cleans quickly. I think there are better but there has been nothing wrong with the one I have.
