If your buck to doe ratio is 2 or three to 1 - I think grunting works if you do it very little and only after Christmas
A doe or fawn bleat will work sometimes on a doe or fawn, but very seldom a shooter buck
Rattling like you see on TV will scare a deer around here to death - usually.... however I have found that occasionally "tinkling" horns together in the early season will bring in a pretty nice buck.
**NOTICE - that I used the words "sometimes", "occasionally", "usually", and "I think" in the above statements.
** and things may occasionally be different in Crenshaw county sometimes. LOL!
