I normally hunt deer/antelope with my 257 Roberts but this year I wanted to try out some future 270 Elk loads using Hornady 150 IBs.
Couldn't get close so I violated my self imposed rule of not shooting critters past 300 yards.
I mil'ed it and came up with 600 yards, measured with my GPS after the shot and came up with 578 yards.
Couldn't really tell what the bullet did, as it only hit the top of the lungs going through both rib cages. Turned the lungs into what looked like old coffee grounds.
In my M-70 Featherweight the Interbonds shoot the same velocity/same place as the 150 Hornady SSTs do I can use them for cheaper practice.
But I agree, the 270 Win is an excellent long range round. My barrel is a 1:10 so I probably wont go heavier then 150s.
