I called up 4 bucks with it last year. I talked a buddy of mine into trying one this year, so he picked one up this week. He called up 5 different bucks this morning and killed a 10 point. He said that EVERY time he blew it, bucks came running in looking for him. Had another buddy call me this afternoon and he said he called in an 8pt that he killed using it. It seems to be better in the pre-rut.
