I have been making calls for around 15 years. I make pot calls, trough calls, trumpet calls, crow calls and have made a couple of duck and owl calls. I really enjoy turkey hunting and being outside in God's creation. Right now I need some information on titanium rounds for pot calls, I've use copper, aluminum, slate, glass, crystal, stained glass but never made a titanium call. Any help will be greatly appreciated. Have a Blessed Day
