With a gun, there are way too many variables for me to say. I have not rifle huntes for nearly 20 years. But I sure killed a ton of critters with them prior to then.

Depending on the type of bullet you are using, the animal could go right down, or run quite a ways.

With very rare exception, the critters I shot with rifles hit the deck at the point of impact. But I could load up some 7mag rounds with say..some 162gr BTSP`s and a big powder charge and pump one right through both front shoulders and it would never mushroom.

If you hit the deer through the lungs(both of `em)it should never make it 100 yards. Through the guts....literally miles if you pushed her.

Liver shot....they are funny. I have seen liver only shot deer go down inside of 50 yards. And I have seen them go for hours. Go figure.

My best advise when using a rifle, if you can`t get one through both lungs....drill `em in the near shoulder bone. It will frag through lungs and heart, and the deer will drop right there.
