How fast can you push soft [almost straight] lead? I want to use it for plinking loads in my .480 ruger. I want to go as fast as I can without leading badly. the reason I ask this is I am very new to casting and know very little about tin and antimony, I am using straight wheel weights, and removing all that floats to the top, then I burn a little candle wax and stir in hopes that I am fluxing, and clean top again, then start pouring bullets in a lee .476 400 mold and my bullets are measuring .477 and fill out perfect. so am I doing this right? I am also new to reloading and these will be the first reloads I will make. I sure jumped in with both feet did'nt I. I appreciate all help, THANKS!!! I am casting at 675 degrees is that about right?
