There' s a bunch out there. Just thumb through an edition of Turkey Call and you' ll see. Try a few if you can and pattern them at diffent ranges (ex. 20-30-40 yds).
As for brand names, I' ll throw these names into the mix: Comp-n-choke, Kicks, Briley (any wing/clay shooters out there?) Rem & Win factory.
A XX Full Comp-n-choke w/ Win supreme, #4 shot is my gobbler " medicine"
