Yep....100 % agreed.Better to have one 0.277” hole in the lungs than one .308” hole in the rump because contrary to what most manly men claim, most of them cannot handle recoil.
But 9 times out of 10 a .270 isn't going to result in 2 holes....
Theres 2 things that matter.
To kill.
and to find the kill.
We lost 2 Elk in camp this year, both died within 150 yards, both shot in the lungs, maybe a little high, both little to no blood trail....Both with 130gr GMX bullets.
If your hunting in thick stuff you almost certainly will need a good blood trail ...at times.
If your rifle, scope fit you and are not ultra-lite theres no reason one cannot shoot a 300 win mag.????
