Why are all new 6.5 CM barrels in stainless steel?

Why don't they make any 6.5 Creedmore barrels in Chrome-Moly-Vanadium (pronounced va NAY dee um for those of you who cannot read - just ask my Inorganic Chemistry teachers)? Especially in the AR-10 world? Is it because of bullet speed and the CMV barrels will not last as long due to gas erosion?

Does anyone know?

TIA,
Jarhead

In a lot of cases the stainless barrels are more accurate then CMV. In 6.5, you are looking for accuracy, not durability and a high round count between barrel changes.

Cleaner machining and better abrasion resistance, read that as better finish and higher round count.
At least according to barrel makers...
Most benchrest or match grade barrels are only available SS.

What is the "higher round count" of a 6.5 CM in stainless steel then? Say in 20, 22 and 24" barrel length?

It also depends on the speed of the bullet. If it goes significantly beyond 3000 fps, it shortens barrel life.

The kind of shooter/gun owner that messes with a specialty cartridge like 6.5 CM normally wants a SS barrel. I know if I'm going to the trouble to spend my time to chamber a new barrel I want the best.

Since I said 'according to barrel makers', maybe you should ask your barrel maker next time you buy one, even if its the first time,,,
