Finally got my spring turkey tag here in AZ. I'll be hunting up north just north of the grand canyon in april, im pretty excited. I'm thinking about putting up a blind and taking my bow.
I haven't hunted turkeys out west but if they are anything like Easterns, I might recommend sticking to the scatter gun for your first. Save the archery for after you have one or two under your belt. Trying to bowhunt them is another league from archery hunting deer and the like.
Take both with you. Anytime I don't have my bow with me on a spring hunt I regret it. Congrats on your tag these spring hunts are getting harder to draw every year. I have used 4 and 6 with good results from both, shot placement is key especially with your bow.
I would get a good choke tube and patern your gun with several differnt loads. It took a couple differnt loads to find one my BPS shoot well. The Kicks gobblin thunder is a pretty decent tube for the money they run about 60 to 65 bucks. They usully have to differnt sizes per gun. Tighter one for 5 and or 6's the other for 4's and or heavy shot.
Shot placement on turkeys is the hardest part(with a bow). If you don't hit them just right they will fly with your arrow, if you shoot carbon you loose 10+ dollars and a bird. I found your post on archery talk also.
I shoot 3.5 inch 2.25 oz of #5 hevishot. Some might call that overkill and it is if every bird is within 40 yards but sometimes hunting public land, things play out a little differently than you hope and being able to put them down out to 60 or so is not a bad deal. I tried switching to #6 shot in the Hevi but it didn't shoot very well and the 5s pattern beautifully. I don't know why but I am sticking with what works. By the way, I am shooting a Benelli SBE2 with the factory super full choke.
