Create a channel Learn moreI thought I read somewhere that the shoulder angle design of the CM lessened throat erosion (over the .260).
And the 6.5 has greater port erosion over time in gas guns. Pick your poison./QUOTE]
Not saying you are wrong, but you'll have to explain that one to me. Can't imagine how the port is going to know the difference between the two. Bullet weight, powder charge, and bore are identical. I could see powder making a difference, but that's not a 260 vs creed thing.And the 6.5 has greater port erosion over time in gas guns. Pick your poison.
As for me, I have both. But tonight my vote is .260 ?
+1 Creed

The science is out their on the CM. Not debating that at all. But it came to my attention recently after a manufacturer submitted a white paper on it to the DOD, during their selection of either .260 or CM. It would seem the straight walls of the case and where the pressure curve is happening is causing erosion that can cause reliability issues sooner than that of the .260. Like I said, pick your poison or do what I did and get both. =)
Why?guys,
The 260 is a better all round cartridge by far.
So, did Mark put out a paper on this? I know he posted it on ARF, but didn’t provide any substantiation other than “this is what I’ve seen”, and I don’t care if others have seen this mentality.
I’d think that him selling a complete 260 and not a complete 6.5 creedmoor plays more of a factor in what he pushes than the case wall shape.
