I haven' t used that call in years but mostly because I haven' t been in a situation where I needed it.It is a great call to use if you don' t have a flock broken up.Many times the whole flock will come in just to watch the fight.To make a good soundin fightin purr I' d suggest usin 2 calls at once,Maybe a mouth call and a friction or perhaps a couple of push button type calls.
