The more that they keep coming out with new chamberings, the more that I am skeptical of anything being brought out in the last 10 years. Now I know that the 308, 30-06, and all of the old tried and true rounds will be around for many years to come, but these new ones seem to only be a flash in the pan. But then again, I just dont have enough money burning a hole in my pocket to justify buying a new gun just because it is the hot new thing. You just dont need a new ultra short rocket launching magnum to kill deer with lol, or even an elk or moose for that matter. Also, if the new things take "special powder" to acheive these hot new ballistics, then why do I want to be tied into buying only store bought ammo to be able to shoot my new toy? I dont know about you, but I just cannot stand paying $30-$50 a box of ammo.
