8mm-06,

A wholesaler will list any rifle in it's catalog that a manufacturer lists in it's catalog. That doesn't mean that any are available. I, or any other dealer can call winchester and try to order anything that I want but that doesn't mean that they'll build it. Again, what they say is available and what is actually available are two different things.

I have an account with Jerry's sports center, unfortunately their website isn't set up to be able to sort by calibers. However, Sports South (who I also have an account with) is set up to sort by calibers. I just ran an inquiry on the number of rifles they have in stock in .260 remington vs. 6.5x55. They have over 150 rifles in stock of various makes in .260 remington, only 9 in 6.5x55. Sorry, but the numbers don't lie, the .260 is much more readily available.
