Well, based on that you should bring them in close enough to use a long bow or speer. Then you'd REALLY be hunting, not shooting.
I'm guessing you don't like the advantage a good scope gives you as well.

My Moose this year was shot @ 6 yards/paces Broadside with Bow(sorry Compound)
Is THAT close enough for ya???

I have contemplated using a spear...but that would be a little dicey!
