6.5CM?

Any top tier mfg like Bartlein, Krieger, Benchmark, etc, etc should work great. Rest of the specs look good.

I can’t speak to custom reamers, freebore etc. I shoot 140’s with my 6.5 barrels and all have been relatively easy to get accurate hand loads in.

If you have access to handle/shoot some of the heavy contours that would help. Depending on what stock/chassis you run or if you have a big can on the end can change overall balance so that may play into your decision on barrel contour.

Obviously a barrel of that quality deserves to be paired with high quality components for the rest of the build to live up to its potential.
