Bruce: Since the Confederates armies were often short of powder, I would not be surprised if regular soldiers underloaded sometimes too. By the way, are you going to continue your guerrilla books for the years 1864 and 1865? I hope so!
Kirby: Good point. If the men were hiding behind fences or rocks, all sorts of material might be flying at them. Plus getting hit by the actual bullet after it ricocheted would usually produce a lesser wound.
