I did see a 130gr 270cal fail to expand on a deer shot with a 270 Weatherby Magnum mv around 3300fps back in 1983.My Dad shot three,times all hit the deer tight behind the shoulder and the deer just stood there as the bullet just penciled through.It did kill the deer,but the wound channel looked like it was made by a full metal jacket.Must have been a bad batch of bullets.t

As Bob Hagel would say"You should not use a rifle that will kill an animal when everything goes right; you should use one that will do the job when everything goes wrong."Good words of wisdom...............
