30-06, 270, 30-30, 243, and a few more are all obsolete. They're not flashy, no mm label, etc, they just kill stuff. I dont know for a fact, but probably 25% or more of the ammo, used for hunting, sold in the US, is these 4 calibers.
I don't doubt your conclusion, but just curious...what is your source for the "fact"?
