I use a 4 bladed, short broadhead, Slick Trick mags, because it flies very well for me. The location of turkey's vitals are not like deer. A sideways shot the does not involve the head should be just in front of the leg a tad above midway, or at the base of the wing. From the back, right up the vent. Head on is trickiest, just below the base of the neck. That big breast tends to confuse beginners, it's a tempting target but more likely to cause wounding it it's hit.
Hunting them with a bow is the same as scattergun but you may need toget them closer. Decoys can take their mind off you.
