Decided to try turkey hunting for the first time this year. Have gotten a Black Hills turkey tag and my group and I are plannin on going out opening weekend. I am just starting to call and have picked up a H.S. Double D diaphragm call (which I am not very good at yet) and a Knight and Hale Ol' Yeller slate call. Assuming I am proficient at each, which one would you prefer to use while hunting? Do mouth calls have an advantage over slate and box calls?

Also, I am planning on using my 10 gauge - are there any loads that are better than others to start out using and see which one patterns best with my gun?

Like I said, I am new to turkey hunting as well as this site and would appreciate any infor you could give me.

Thanks
Mr.G
