The NO. 1 tip for bow hunting turkey is to buy stock in the manufacture of your arrows and broadheads. You will need it.
But seriously with all the new bows out with 70 to 80 pound draw weight is not necessarily a great thing. But the higher let offs will be.
Most of the time you have to pull back a lot smoother and slower than you would on a deer. Then you have to wait for the correct shot. Maybe holding for 2 to 3 minutes and even having to let off then pull back again.
So a low draw weight of around 50 lbs is what I would recommend. Of course that is going to be personal preference. Personally I have my bow set at 55 lbs. The low draw weight also lowers the chance of a complete pass threw. Which helps keep the bird on the ground.
Broadhead is a matter of choice. I have used a fixed blade broadhead and have had great luck with deer and would never change, but they are not for turkeys.
I have a few Rocket Buckblaster with 3 fixed blades and 3 mechanical blades will be one of my choices for turkey this year. It has a 2 1/8" cutting diameter, and will give the best of both worlds just for turkeys. But are very fragile tip if it hits a limb or shooting at a deer. So it becomes a one use item.
Another thing that should help you bag a turkey this fall are turkey arrow stops if you want to keep your fixed blades like I do with my Muzzy's. These are made to keep the arrow from passing all the way thru. But limit's you to a one use arrow with these stops.
In the old days they used to take bottle caps from sodas and punch a hole in them and put them behind the broadhead. But the aerodynamics of the arrow would change dramatically.
I have even heard of putting washer behind the broadhead for the same purpose.
Also what looks to be interesting is the new Broadhead I have been seeing is the RAZORRING Broadhead it also might give the best of both world with the new ring that cuts behind the three fixed blades. Hopefully I will get a chance to test these out this year also. You also gain the dual purpose for the use on turkey or deer. Also I believe they might be the future of deer hunting broadheads only time will. Either way they look awesome.
No matter what your set up is you need to decide before the season gets any closer.
You will need to practice shooting a small target, about the size of a tennis ball. Practice makes perfect plus we owe it to the game for a clean kill.
Also remember you are going to have to be able to call without using your hands.Using a mouth call or being able to call naturally will give you those last few steps or call the whole group within range.
Also do not leave any details out like your eyes or hands when you go to camoflauge. The eyes of the wild turkey are its greatest defense. Could make all the difference when it comes time to pull back.
Unlike deer hunting when the wind is blowing I have found to be the best time to hunt turkeys. You movement does not show up as much and if you try to stalk it will cover up some of your noise in fall leaves.
But, I believe the ultimate challenge is shooting one turkey out of a flock of 15. That makes 30 eyes out of one of the most paranoid game birds there are.For most of use we could go all are lives hunting turkey's with a bow and not take one.
If you don't think it is hard. Just try to find a hunting video or watch on TV the professionals shooting turkeys with a bow or find a friend that has shot one. It is almost impossible to find many people that have tag one of these birds. If it were easy for everyone would be doing it.
The reality of it is that you need a good recipe for the unused tags you will have every year. But when you do get your bird it is quite the thrill.
