The vast majority of hunters aren't rifle loonies, don't reload, don't practice their shooting skills (or lack there of) regularly, and probably shoot less than 20 rounds per year of centerfire ammo. For them, factory loaded ammo that is cheap, widely available, and kills their game of choice is a factor in their rifle and cartridge combination of choice, that is why rifles chambered in 223, 22-250, 243, 270, 7mm RM, 30-30, 308, 30-06, and 300 WM sell so well in the contiguous 48 States.

It seems that I was destine to be a rifle looney as my first 10 centerfire rifles were chambered in 219 Zipper, 222, 22-250, 6mm, 25-35, 250-3000, 257 Roberts, 7x57, 308, and 45-70.
