The test was done at 80yds away. Next time I go out Imighttest the 435gr Buffalo Bullet and the 310gr Buffalo Ball-et no matter what. I am a little un sure about using a hollow point on elk but I think i would get a pass thru or maybe find it on the other side under the skin. I know that I will use that for deer but for elk I might use the 435gr Buffalo Bullet RN HB. The Hornady is about 7/8" tall and the expanded one was 7/8" wide. A quarter is about 7/8" wide to. Do you guys think I could use that Hornady on elk and Moose? If that conical could break thru thick plastic it should do fine on elk and Moose. Thanks for running those ballistics by the way.
