Iv'e taken 40 or so with my Winchester model 70- 270 using the Winchester 150 grain. great combo, but I think any of the 130, 140, 150 grain are fine. Just don't gut shoot it, bearly leaves a hole so you will not get any sign. Watched a friend hit a gutshot by the deers humping up when hit and it was a lost cause.Have had a few bullets come appart and blow fragments back into the stomach on a good broadside chest shot, What a mess. I like the flat trejectory best, just put the X where you want the bullet to goand squeeze!!!
