Because of mono bullets and penetration, I think a lot if people look at anything from 243 to 7mm08 as being capable of handling the same animals. AKA I don't think new/first-time rifle buyers are looking for multiple, specialized rifles. And the 6.5cm is the current "pound for pound" favorite. But 708 handles much heavier bullets and isn't going away. Wal-Mart near me doesn't carry several other cartridges that aren't going away either -- they just push what they can flip at highest volume to max profit. It's why they sell plastic and Beechwood rifles from Savage and Remlin, too.
