I got around to shooting that Model 10 this week, and thoroughly enjoyed my limited time. I slipped off to the indoor range on a lunch break and spent a half hour with a box of Winchester White Box 130 grain ammo and the old revolver. I readily admit that it's been a long time since I shot a revolver, but the results aren't half bad. The vast majority of the body shots were at 25 yards, the max range available at the indoor range, and the head shots were at 15 yards. The target, or course, is a standard B27 target.
Of course, there are very few skills that erode as quickly as proficiency with a handgun, and I readily admit that I don't spend enough time with my handguns. It's been 10 years since I even picked up a revolver for any serious target work. Still, it was fun to get out with the old revolver.
