Sorry but it is too much fun poking the guys who can't imagine an elk could actually be killed with anything but a mega magnum.
I mean an elk is simply a magic creature that actually knows what it has been shot with. Wrecked hearts and lungs are not the point, it will not die until a minimum cartridge has been used.
Magic is cool.
There 'ya go right there and said very well 'lil John,wrecked heart and lungs mean nothing..I have seen the 22-250/223 and 243 used on Elk and in what I have seen,the .22-250 and 223 killed better than the 243..Just because of the user putting the bullet where it belonged..
It isn't the caliber but the shooter being able to make the shot needed without stressing out....The differeence between the 243 and 223 is so small,how could it matter if they both penetrate the same?
