April 21 is the DAY...In Missouri at least.
I have tried three seasons to kill a turkey with my bows. I was able to draw (without a blind) on only ONE bird. The arrow was deflected, but great fun anyway. Turkey vitals are about the size of a softball. Practice hard on picking the correct spot. Any sharp broadhead will do the job if placed properly.
These birds can see you blink at 30 steps. If you really want to take a bird your first year... buy a good blind; practice shooting out of it and set it and your decoys(facing your blind) up in a good spot. In my opinion a blind is the best way to go with a bow.
I will be out the morning of April 21st with my 12 guage. Then the 2nd and or 3rd week with a longbow and a shaggie suit. Blinds were just "no fun" for me. I felt as if I wasn't in the woods while in a blind. Blinds are deadly effective for birds.
good luck,
