Ron the target above is pretty darn good for the start of practice, off hand, especially under the weather circumstances. Now to head some off before they state, 'Well its cold during hunting season'. No disagreement. But starting to learn/change at this time of year, won't be as easy starting as it will in the spring.

I know guys that can shoot darn near a single hole 5-shot group at 50yds and a little larger at 100yds. NOT ME!
I do know how they prepare themselves. They take the hand held weights you see the preppies with, and hold them out at arms length, straight out in front of them. One in each hand. It builds up their stability.
