"That's ignorant.", I agree.

"shot placement trumps caliber every time", I also agree.

If the old 30/30 and its black powder predecessors can do it, a 7-08 sure can.

I think those who used the 30/30, etc. 80 plus years ago weren't ignorant enough to think you can buy hunting skill with a bigger gun or any other hunting tool. One of the farces that our prosperous society seems to have a lot of is that of buying yourself into being a better person...and I'm not just talking guns.
