Allen,

I have tried the A-Frame in my 270's, but as I recollect I've only shot one animal with that combo, a mule deer. I wouldn't hesitate to use it on plains game though. I rarely ever use 150 grain bullets in the 270 as if I feel the need for more bullet than the 130 grain, I just move up to the 30-06 and shoot 165s or 180s.
