Gunsmithing Which rifling from Benchmark?

[sobrbiker883]

I'm gonna get a Benchmark barrel for my 6.5 Creedmoor (140 Amax 2800fps) and the ol lady's 6XC (107SMK 2975fps).
I've always done 5R cut rifled but am considering trying 3 groove since Benchmarks are button rifled.

Input and experience?

Call Benchmark, those folks are a pleasure to speak to on the phone and will answer any questions you have.
