Probably most of us have more than one shooting or shooting related past time. I read some of the earlier posted topics regarding "runnin' ball" and swaged balls.
One of my other shooting past times regards shooting Sharps rifles, casting and loading for them.
When casting balls or bullets if a dipper is used such as the Lyman or RCBS you can keep the spout in contact with the sprue plate which allows the weight and heat of the lead in the dipper to continue to feed the projectile and pretty much eliminates inconsistencies in projectile weight. Using this method those of us who cast heavy bullets, 400 to 600 grains in weight, can keep our weights within 1-3 grains per projectile per casting session if equal attention is paid to temperature and the length of time the dipper is held to the sprue plate. Once a rythym is achieved this variance can be held to around 1 grain. That's pretty close casting. After cooling all bullets are weighed and segregated according to weight and the ones with obvious deiscrepencies put back into the furnace. When loaded the finished cartridges are also segregated. If accuracy is to be achieved at long ranges this is necessary.
Just a few thoughts on casting lead.
