I love the gobbler guillotine arrowds.com There a bit pricey and I shoot them with a 32" forward tapered arrow that can be purchased through Cabela's. I practice shooting at hanging carrots and celery.
I use the same broadhead as for deer, a Magnus 125 grain, the wide one. And as turkeys are hard to put down with a bow I ALWAYS use a string tracker. Saves a lot of birds from being lost.
