Pupper....good answer, just what I would've said.
Wayne....
It's like knowing where your rifle hits if you're dialled in for 100 yds and you aim at something 200 yds away. You've got to know where you're hitting in case the animal isn't standing exactly 30 yds away.
Broadheads do act differently than field tips. Get your X-bow set up for hunting and shoot the broadhead (you only need one ) until you know exactly where they are hitting at 20, 30, and 40 yards.
It'll take probably 4 phone books to stop your broadhead. You can then re-sharpen it and hunt with it.
Good luck
Dan.
