RE: Short draw when cold.
Here' s a little tid-bit of totally useless info for you. It takes your muscles 3000 repetitions of doing the same movement to create an " imprint" on that muscle, so it does it every time without thinking about it.
So, I guess what Chad says makes alot of sense. If you practice good form when at the range, it should come naturally in the field. I think I have like, 2000 more repetitions to go.[:' (]
I know if I sit for extended periods of time in cold weather, its alot harder to shoot my bow. I guess I need to do some little exercises to keep the muscles warm as well.
