You can get them all season long, but your tactics have to change as they go thru the various transitions, plus hunting pressure and weather can effect what you do to be successful. As mentioned earlier, the general rule is call softer and more infrequent as the season goes along, especially as they come in. Also use a call they may not be used to (wing bone, tube call, etc), and call in a different direction they may not be used to. If that doesn't work do something different ... like throwing a turkey fight with a couple push-pulls doing aggravated purrs and occasionally throwing in some excited cutts on a mouth diaphragm and a few hat slaps simulating beating wings.
