From what I know or think I know:

1) During thepre-rut phase you rattle lightly.

2) During the scrape phase you rattle to mimic actual all out fighting.

3) During the chase or primary breeding phase, same as above.

4) During post rut, rattling not as effective.

5) During the 2nd rut, rattling may be effective once again since there are less does to be bred thus creating even more competition between the bucks.

So my question to you is.... During which of these stages do you add grunting or perhaps even a combination of snort wheeze and grunting? How about doe bleats? What sequence and what combination during what phase?
