Funny story: I bought a call that was a grunt on one end and a snort/wheeze on the other. Sitting in my treestand on November 15, a real big boy came running past, nose to the ground after a doe that had just gone by. I decided that THIS was the moment for the snort wheeze so I reared back and let one loose-- from the wrong end of the call! Instead of Ffft--fft--ffft--FFFF it came out erp--erp--erp--ERRRP. Forunately, he could have cared less about whatever sound I made--the doe was hot and he wasn't paying attention to much else. I was glad there were no human witnesses......
