My first ever cast boolits were done on a old charcoal grill, with a small cast iron pot and a ladle, made 200 lee 230 grain round nose tumble lube boolits for my 1911, once I got everything hot enough pretty boolits started falling out of my mold. Was HOT sweaty dirty work and lead spilled everywhere a few days later got my first bottom pour lee pot, much much better. I elected to try the old grill over a fire so I wouldn't have to squat on the ground and I reckoned it would be easier to control temp by adding a few briquettes at a time and being able to put the lid on. I was sweating like a pig, and only by dummies luck avoided a Vista from the tinsel fairy.
