Anything that is rubbing two surfaces together to produce sound is a friction call.

I've had the same experience for the most part. It seams that you can strike a Gobble using a locater, move in adiquitly and set up. Give a few yelps with the mouth call ...... and nuthin. Wait a bit, hit the box call and that son ova gun is Gobblin his head off.

Do you supose it could be that mouth calls have become so popular, they are getting hit with them too much?

I guess thats why I have a vest full of calls, and give em what they wana here.
