Keep practicing - it takes a long time to master, but it will ultimately be your favorite call once you get it down.

Even after you get good at it, it's still tough - last year, I called in a really wily old bird and he was about 10 yards away, just over a break where I couldn't see him. He was gobbling like crazy for about 20 minutes and I got so flustered and cotton-mouthed, that I couldn't make a decent purr to save my hide.

Needless to say, he lived to see better days... and well... I never did get that turkey. Had to settle for a different model.
