I put my bows down for 2 months, Feb and March. I need the mental break from hunting season since I bowhunt the month of January in Jersey.
I pick the bow up in April and prepare for spring Turkey, then put it down June/July when the bass and walleyes are biting. I look forward to not shooting every day, an escape from the mental aspect of making every shot count.
August rolls around and I start a slow process of warming up in the shop basement shooting 5 yds into my bag. Slowly working the form back...draw, anchor, pick a spot and clean release. I then make my outside practice fun and realistic. Shooting judos at leaves, stumps, birds and woodchucks.
I find shooting distance, like 40-60 yds at small objects makes me concentrate more. To me it makes those closer range shots easier. It's all mental.
By the time Mid September rolls around and CT and Jersey deer seasons are open, I'm both physically and mentally ready to kill. It's even better when my buddies and I make our annual spring bear hunt in Canada the first week of June.
I would say the most difficult part of regaining the "shot", making sure I'm at full draw and concentrating on my intended target. That changes however with repeated shooting sessions where I never put any pressure on myself to "10 Ring" everything.
