Here is my first question -223 small varmints, 243 or 270 both-varmint&deer/utility/"tweener", 270 or30-06 big game, 308 or 300 or 338 or______ dangerous game?
Is 243 and 270 a must?
Just wanted to make a couple quick observations here. First, if you have a .30-06, there's really no need to add a .270 to the mix. It's a bit redundant.
You should have the .308 in the same category as the .270 and .30-06, not with the .300+ Magnums.
For a cartridge between .223 and .30-06, that uses bullets between 55 and 100 gr., you're pretty much stuck with .243. That's about the only one I know of that fits your description. And, you're not really "stuck". The .243 is a great round. I've used mine on game ranging from jackrabbits, to wild boar, to whitetails, and it's performed perfectly on all of them...
