I like any kind of slug. My question would be penetration. It looks like it would work, one ounce at 1,600 fps. I'm thinking a Brenneke slug would be a better choice. As I understand it, the PDX ammunition is for self-defense, not hunting.This is a pretty good review

But still, it should work for a deer.
