Bead bags do work quite nicely, for all injuries, not just firearms injuries. The basic idea is that you dont know how serious your wound is until someone with a bead bag reaches you (for example, a healer). I've seen them used in various guises, from a bead draw for all injuries to bead draws only for wounds that are left untreated for X amount of time.
Its a good system because it assumes that the average person doesnt know how serious his/her own injury is. _____________________________________________________
