If you were hunting those dates in Indiana, I'd tell you that's prime time, pre-rut and into the rut good. The deer are chasing does looking for the first receptive ones and still fighting with each other. Toward that end, treestands with grunt calls work best for me. Maybe an estrous doe bleat toward the end of your hunt period. I use real subtle grunt for the most part, and usually only on bucks that I can see, but want to bring in. I only use it if it doesn't look like they are going to give me a shot unless I do something. Make sure you have a shot between where the buck is and where he would catch your wind if you are going to call. Whiteys are pretty patterned and predictable...until the rut, then all bets are off.
Good luck and have fun. If you're hunting from a tree I can't stress enough to wear a full body saftey harness. Either use the harness or sit your butt on the ground.
