Hey guys I was wondering if anyone would be willing to part with some information on a Jordan Style Yelper. I am not looking for any specifics just a general idea. My question is?? About how large is the inside diameter and length of the hole in the largest section of an average Jordan style call?? I know these dimentions vary but I am just looking for a general idea. Any suggestions or ideas would be greatly appreciated. Thanks and I understand if no one wants to part with any information!!
