RE: Guillotines and how much they drop?
Definately DO NOT try to shoot 30 yards with these things, they just dont fly THAT good. Up to 20 they fly just about like a field tip but i would still recomend shooting them first to practice. Make sure you definately have the "straw" like covers on the blades. Without them they wont fly right. Personally if i were using them i would be in a double bull and have the decoy at 5-7 yards to ensure a close shot!
Good luck!
