Jeff,
Remington and Winchester don't dominate the rifle market as they used to.
Major European companies are now chambering rifles for the 6.5 Creedmoor. It's not just starting to become a standard American chambering, but world-wide. Of course, part of the reason is the U.S. being the largest rifle market, but the fact remains that European gun companies have a better idea of what's really going on than many Campfire members. I know this sounds strange, but it's true.
Despite its usefulness, I don't think that the 6.5 Creedmoor will reach the level of success/distribution in the U.S. that the 223, 243, 270, 7mm REM MAG, 30-30, 308, 30-06, and 300 WIN MAG have.
I can only report on what I see, and I what I see at the range and in gun racks are bolt action rifles from REM/RUG/SAV, lever action rifles from HEN/MAR, and semi-auto ARs. The only 6.5 Creedmoor that I've seen at the range that didn't belong to me was an RPR. I don't see many European rifles, a few Sakos, or Asian rifles, a few Vanguards, here in Nebraska. I travel a bit in the Midwest, Colorado, and in New England and I'm not seeing 6.5 Creedmoor rifles in the new/used racks or factory ammo on the shelf of small/local gun shops in those states either.
I'm not anti-6.5 Creedmoor, I currently have 7 of them and hope to buy a couple of the RAR 16942 style when/if they hit the market. I think that the factory ammo is great and I've shot a couple of whitetails with the 129 grain Hornady American Whitetail factory load from an RAR-P last fall, so I think that I'm doing my fair share to help it along.
