if one looks at ammo availability in the store, the obvious conclusion is we continue to use the same standard rounds (7mmremmag, 30-06, 270 win, etc) we have used in previous decades. while there is more .223 ammo and a better selection of same in the store, i attribute that to the very large numbers of ar's sold in the past 2 years, as in 223 ammo bought buy new ar owners who just want something to shoot. i don't think we are gravitating toward smaller cartridges at all. perhaps some see a small trend based upon some posters, but if you look at the ammo wmt has available or sold, the standard rounds are still king. jmo.
