I use a similar method of that of shed33. I hardly get out to shoot in the winter time because it gets so darn cold here and I do not shoot in an indoor range. I usually start shooting in june at least once a week through July. When August rolls around I go out and shoot just about every night if the weather permits me to. In the week before the elk opener i shoot like a mad man usually twice a day. I want everything bang on for that opening day and my confidence level high.
