I'll be bowhunting with a crossbow this year and I'm seriously thinking about shooting the muzzy original 3 blade broadheads along with a mechanical broadhead so my question is this, after sighting in with field tips will my fixed blade broadheads shoot the same as my field tips? Or would I have to readjust my scope to get my fixed blades to fly true? I'm wanting to be able to switch from field tips over to fixed blade and mechanical broadheads without having to readjust my scope so any help and information would be greatly appreciated.
