I use any expandable that shoots really well for my bow, then i hit the blades with a file to dull them on purpose. one thing to keep in mind when turkey hunting with a bow, try to not shoot one in areas where you have thick timber within about 100 yrds. A lot of birds shot with the bow will fly off for a short distance, their leg will be hanging if they are mortally wounded and you have to try to watch them till they go down. I grew up in a state with 5 tags and pretty much tagged out every year and then went to adjacent states to shoot a few. 20 yrs ago, i wanted to start bowhunting them and i had good success on a few then lost 2 in a row. I put my bow up for a few years after losing 2 old mature toms. That said, i prefer archery over guns for about any animal, but there is a reality of not recovering bow shot turkeys if they fly off into a swamp 40 yrds away. In more recent years, i went back to my preferred bowhunting but i limit myself to not shooting in areas that i cant find the bird if it goes 100 yrds. Some will never go anywhere, and others will fly off if your shot is just an inch or 2 off....i also try to always shoot at birds standing sideways to pin the wings and i no longer shoot when they strut so that i can better see the true body outline.
