Just back from Mont. where I killed a Mule deer buck at 230yrds, using my 7x57 and 140 grn Bergers, MV 2850fps. Deer quartering away, hit to place to bullet in opposite shoulder. Did just that, mushing up lungs and heart, coming to rest in hide. Perfect mushroom, weighed 63.1 grns. Also killed a coyote at 360yrds, slight quarter to me, bullet hit just behind on shoulder, through rear chest cavity, blowing out insides and exiting right rear taking right hind leg with it. I say they work.
