I bought a rabbit in distress call, its a PC-7, and i can't get it to sound right. I went out to see if some crows would come in and they never came. How do you guys calls for 3 minutes with out stopping completely to take a breathe? i can only got for like 30-40 seconds before i gotta take a breath. You guys go anytips on making this thing sound right???? i got a rabbbit in distress tape i listened to for a little bit but i can't make it sound like that. DO I blow hard soft to i put my hand over the call a little or alot. and sounds i should make while calling. ANYTHING would help me out a ton.

Thanks
