I've been ladle casting RB's, conicals, and CF pistol and rifle bullets for ~50 years with few difficulties. However, yesterday (Oct. 3), I cast a bunch of .550" RB's from a Lyman mould* and got the smallest weight variation ever from that mould. I paid particular attention to the temperature of the melt and the size of the sprue puddle and got very few rejects (wrinkles, lighter weight). Those that were too light were no more than .5 grains (out of an arithmetic mean of 255.1 grains). The lightweights will be used for fouling shots.
*The little used mould, which I picked up for a pittance, is for the .56cal. Renegade Smoothbore. It needed a tiny bit of TLC when I got it, but it casts great now.
