I have had a S&W 386 XL Hunter in .357 Mag. now for almost a year and I love it. I shoot it well enough but would like to get better. Lately I have been trying to shoot longer ranges (out to 100 yds.) thinking it might make me a better shot in closer but I seem to have hit a wall. I would like to tighten my group at 50 yds. (my self imposed limit to shoot a deer) but 6" is about the best I can do. Anyone out there have any tips they could share or books to read with some good advice in them? TIA!
