Number of times I have blown a grunt call: Countless
Number of times a grunt call has worked (in such a way that I could say it was definitely the proximate cause of a deer appearing): Zero
Number of times I have clanked together the rattling horns: Countless
Number of times ratting has worked: Zero
Number of times I have hit the doe bleat can: Countless
Number of times the bleat can has worked: About SIX times.
However, what it brings in for me, so far, is just yearling or 2.5 year old bucks, or a fawn.. and once another doe. So I usually pass on what it brings in, but it does work sometimes.
