Given the current fuzziness involving these newly "invented" cartridges appearing on the market, it is not easy to see the future or guess what will vanish over time. It is certain that the good older ones have not vanished, as seen in this thread. I will be long gone when the dust settles on this issue, and probably so will quite a few of you - but can offer an opinion based on experience. If we are still shooting/hunting and competing 25 years from now, some of our stuff invented in the late 19th and early 20th centuries will still be in heavy use and quite effective in comparison with these newcomers. Like - 30:06, 7X57 Mauser, 6.5X55 Mauser, and the older take-offs in different calibers as based on those cases. And a few more - like the 22/250, .223W, .22 Hornet, etc., etc. And, a few of the old Magnums too. Just an educated guess.
