imo, there is nothing better than woods roving for practice and tuning up for hunting. relatively short and fixed distances help with form.
the key is to be in the hunting element, for best hunting practice.
that means, if you mainly hunt from the air, get up high (tree, ladder, etc) and practice. for ground spont 'n' stalk, nothing beats roving and varying targets and body positions.
it also greatly helps to shoot just the same bow and arrow type all the time. familiarity breeds accuracy and confidence.
