RE: Broadhead practice
Practicing with broadheads can be a real pain. I have had a couple of bows that for some reason would not group exactly the same with both broadheads and fieldpoints. I never thought about using two sights! I would just sight in with the broadheads, then have 2 or 3 arrows reserved for practice. I would only shoot maybe one or two arrows a day during the season to make sure nothing was wrong.
I don`t shoot too much with broadheads even when they hit the same as my field tips. I like to use thunderhead 125 gr. heads, and they fly fantastic for me, but they won`t take alot of hard impacts into a target before they spin less than perfect. I have used TH`s for so long that I can tell by the way they spin on a shaft whether they are gonna do their part or not.
