timber, if you don't know, wouldn't that alone make it unetchical?

Take me for instance, I don't know if I could hit a deer at 100 yards with my bow, would it be ethical for me to try? I don't think it would. Even one more step up, actually I know I could but not every time, again, I have no business trying it then right?

Now, there are some excellent marksman out there that shooting a rifle at a running deer is second nature to them. In converse, some have no business shooting longer than they do as well. But that's another debate.
