I swear by the Magnus Bullheads and heavy arrows. I used to shoot traditional bows, and just grabbed my old arrows (full length) with 5.5 inch feathers and those Bullheads by chance shoot lights out to 25 yds easy. I have hit birds low, in the wing butts (bad shots) and still anchored them. I have not lost one bird nor missed a bird with a Bullhead. I normally set the decoys in front of my blind at about 8 steps. I don't know how they do with light arrows, but with those heavy arrows and close shots they simply crush the birds.
You can see arrows in quiver. Hard to miss them when they're like this.
