I once read an article about how they used wax bullets with fake blood in them to make old movies. And do live reenactments, like at boot hill. They would put thick padding under the actors cloths and have sharp shooters just off camera do the actual shooting. Also talked about the shooters using light live loads to shoot windows and kick up dust and stuff near the actors. Sounds a lot more sporty than the electronics and squibs they use today.
