I started learning about turkey hunting by watching some of the tv shows and then I went to the library and got out as many books as I could about it. I also bought a few tapes.(Got quite a few now

)
While the TV shows are okay I would recomend "So you want to be a Turkey Hunter" tape from HS Strut to start out with.
You should also think about what calls you are going to use. Box,friction,diaphram and push/pull calls are the various choices. Since I have "gag reflex" I do not use diaphrams. I use box and friction calls. Once you decide what you prefer .....practice practice practice. There are many types of calling that you will need to learn...yelps,clucks,purrs and many others.
Then you have your shotgun patterning to do.

You have to pattern your shotgun to determine what shotshells perform the tightest pattern in your gun. You also should get a turkey choke that will tighten the pattern up even more.
I have only touched the tip of the iceberg Jason......there is alot to learn .
