I've been wondering of late, what will the gun and hunting magazines talk about in 20yrs? Will there still be articles about the "tried and true 30-06" or "still 308 WINning, after all these years"?

If we look at trends in recent decades, development has tended to focus on super magnums (used to be shorts, now full lengthers) in middle-ground small bore calibers (6's and 7's) and standard or short length mid-bore cartridges (Ruger RCM's and safari mags, 338's fed & edge, etc), and of course, the proliferation of "MSR cartridges".

But does any given cartridge or class of cartridges have the the market saturation that the 308win or 30-06 (and their families) had through the 20th century? Will the magazine articles 20yrs or 40yrs from now talk about the 7mm WSM or the 26 Nosler as the cartridges of yester-year, the way we talk about the 30-06 or 308win now? Will the 30-06 and 308win only remain with the last few hold-outs stuck in a time loop, regarded in the same light as today's levergun hunters sporting 30-30's or 45-70's? Does any cartridge on the market today enjoy enough popularity that it will be the "cartridge that keeps on giving" and carries through the next generations?

Then again, maybe there won't even be magazines to be read anymore in 40yrs. He11, Playboy already gave up to the internet...
