A friend makes his own traditional beeswax-and-mutton-tallow lube and his own "cartridge" boxes for cap-and-ball revolvers. I asked him where he got his tallow and he mentioned US Wellness Foods, adding that now is a great time to buy mutton tallow because they butcher a lot of lamb for Easter. Just thought I would mention it.
