I have called in bucks in the early archery season, never anything big, some small 3 and 4 points, and tons of does.
It will also work in the late season. When I lived in Utah
I once jumped a bunch of deer in some thick cedars, and sat
down and started calling. I sat there for about a half an hour
and the deer started filtering back in and there was a very nice
buck with the does. It seems to work well before the does drop the fawns, but in the 2 - 3 week slot when most of the does are fawning it seems to drive them away. After most of the does have dropped it seems to work good again.
