As an experiment, I loaded up a dozen of the Hammerheads with point weights varying from 125gr to 300gr and the stock insert, and shot them out of my Adcock 64#@31". At 15 yards and under, they all shot within a 6" circle. At 20 yards, I saw the effects of the heavier points. The heavier ones had progressively lower points of impact, but the windage was the same. I settled on shooting a 100 grain insert and a 125 grain head. Alternately, I can shoot a 200 grain head with the stock 25 gr insert. Full length, they weigh right around 700 grains.
I have a 53#@31" HH longbow, that I can shoot these out of, but they do hit a little left and are really too heavy for that bow. I'm going to try some of the trad lights for it.
