RE: Winchester Supreme 140 gr Fail Safe
its my understanding that they are made for larger game and made not to expand a whole lot but to penetrate and bust big bone etc. if used on deer they will kill it. put it right where it needs to be. but it may not expand much at all compared to other bullets. it will most likely blow right through...but holes through the vitals is a dead deer..good deal though...i wouldnt passed it up either way.
