It's more to do with where and when then how as far as deer calling goes. It's a pretty basic routine really that we've all seen on many shows. It boils down to Buck to Doe ratios if you've got lots of does and few bucks there is little competition and it makes for poor calling. As well as time of year, peak rut is not peak calling season for deer. The 2 weeks and in particular the week before the start of the rut is prime rattling. This is the time boundaries are established and dominance set. Once the rut is on they are busy, this is not to say they won't come in but best action is definitely just before the rut.
