Gunsmithing Grooves for 65 Creedmoor and 6XC

[sobrbiker883]

I'm gonna be picking up a barrel for both my 65CM and my ol lady's 6XC.
What are the hot tickets for rifling these days? I've always ran 5R, but have been thinking about 3 or 4 groove. Search didn't help me too much.

The 6XC runs 107SMK's and my Creedmoor runs 140 Amax's but may be going to Berger Hybrids......

I've used 3, 4, 5R, 5C, and 6 groove. No discernable difference on the range. THe only have noticed on average is that the 5 R and 5 C seemed to clean up a little easier just due to the lack of tight corners in the grooves. Although a couple of my 4 groove ones cleaned up just as easy.

even number of grooves, the lands oppose eachother. Odd number the lands oppose a groove. I have heard that a odd number causes less bullet deformation than even number(made sense to me). I tried a 3 groove for my 6x47Lapua and have had great results but i cant say anything bad about the 4s and 6s I have shot....

Get a 5 groove for the 6mm 7.75 twist, the manf. you're looking at doesn't make a 3.

3 groove 6.5CM here...no complaints at all with cleaning or accuracy.

Have a 4 groove krieger with zero complaints of cleaning or accuracy.

4 groove kreiger, ask Blackops (Mike Resigno @ TacOps) on here why.

 

[sobrbiker883]

That would be pertinent information, had I been asking about Kreigers...you don't get bonus points for swinging on Mike's nut sac.

Wow really, you should probably just run a 2 groove no name brand then...

Gray-
I guess I owe you an apology, I had thought that I had specified I was looking at Benchmark barrels in my original post.

My hackles have always gone up when I hear "(big name) uses (such and such)" online...
