I have made a ton of mistakes in the past, here are just a few.
1. always look around before you start to rattle and make sure you do not have one standing in bow range already
2. Set up in thicker cover, make the big one come look for you. If you are on a field edge, a decoy helps tremendously.
3. Raking the tree a minute or two prior to a simulated battle will sometimes draw in a buck to investigate the "deer" rubbing a tree. (Refer back to #1 before you start your rattling sequence"
4. Pause occationally during your rattling to listen for a deer coming and keep your eyes open while you are beating the bones together.
5. Too late to do it now but you can use some wood stains on natural antlers to have a camo effect and loose the white of the bone. In otherwords, if you have dark sheds, use them rather than the bleached ones. That buck looked at me like I was trying to flag in some snow geese.
6. If a deer is moving away from you because you have already messed up, ie, sees you in the tree, do not pick up the horns and try to call him back, it only educates him and makes him nearly uncallable in the future.
I can go on and one with mistakes but these are ones that have cost me big bucks in the past. #1 was just plain stupid on my part, a 160 inch 10 pt. For each mistake I have made, I have had a good learning experience to walk away with. Have fun with it, don't over do it, and if you ever get a chance to see and actual buck fight, you will learn more about tecnique in 30 seconds from that than anyone can ever show you with sheds. I have been fortunate enough to witness two full blown fights lasting over 3 minutes each and have heard 5-6 more from a distance........Good luck with it
