What do you guys see happening in the future with all the new short mags. and caliber's introduced recently? Will they stand the test of time and be around 20 years from now? Personally I think the old calibers such as the '06, .308, & Win. .270 will still be up there as the more popular rounds. If any one wants something a bit more powerful I think it will still be the 7mm Rem. Mag., 300 Win. Mag., & the 338 Win. Mag. If I had to pick the smaller calibers I would go Rem. .223, Rem. 22-.250, Win. 243. I still don't really see any of the new calibers knocking any of these 9 rounds from the top 10 in the next 20 years or so. Any picks from you guys from the new rounds to make it long term?
