Back when I started I made up for my lack of calling skills with scouting.

If you scout enough and find where the gobbler likes to strut,you can score on some birds.

Calling will come to you over time as you listen to birds calling,scouting will keep you in the game.

Scouting can be as easy as leaving early for work and driving around looking for strutting birds.
Or sitting on a ridge with binoculars.

Ten years in now and I'll be out before the season driving the backroads.

Good luck
