The time of year dictates the type of call/lure.
Calf bleats/distress will almost get a response all year round, from does of course.
You can call too much also.
Earlier on it should be less aggressive and sometimes only a single doe bleat or grunt.Study the types of grunts and bleats and how to use them, too many for me to list.
Close to and during the rut you can become more aggressive as the animals do the same.This is when I find it is best to rattle, only at the peak of activity.
A dominant or aggressive buck in the area really does not want you at his does and with proper technique he will come blasting in and try to find you or at least drive you off.I have had bucks do complete circles around me and go grunt for grunt with my grunts, be this as it is, they are still cautious and won't expose themselves too easily.
I quick grunt can also stop a deer in it tracks if they are on the move.A properly done series of grunts will have them coming to see who you are also.
The one thing I must include is to watch your wind while you do this.Use it to your advantage, and don't get caught up in hardwoods or realtree camo as well as covers scents, washes , anti odor products etc.They all work great for hiding from people but deer have those damn noses and ears that you can't trick too easily, and, they don't see the color patterns in camo, you could wear a clown suit and call in white tail.
