There's a considerable difference between "ding" at extended ranges and "rocking the steel" with mass and velocity!!

That gets lost somewhere along the way.
Good point.

Big difference between ringing steel and dumping critters at 600. I've done a fair amount of the first.... and very little of the second.
For steel and vermin... I'll take a mid-size 6mm or 6.5mm all day.
For pretty much ANY big game hunting.... be it 60 yards or 600 yards.... pass the 7 Mag please...
