I was sceptical about calls for a long time, but in the passed few years have learned from experience that they work. Have killed several deer while using them. Best one was last week when I used a combination grunt call with a doe bleat can. Had a nice 5x5 buck come right in to me after just one sequence of calls. It took about ten minutes to get the buck in. See picture in " A Good Day Hunting" in the rifle hunting section of this forum.
