My cast bullets have been coming out wrinkled and inconsistent. I am using 1 part lead to 1 part Linotype. I am casting .309 and .312 bullets for rifles. I have a PID I am setting at 725 degrees. I use a bottom pour Lee lead pot. I am using 3 Lee 2 cavity molds and one HM2 5 cavity all aluminum. My current process is to use two molds at a time. Fill them then I let them cool on a metal ledge before water dropping them. While the first two are Colling the next two are sitting on a hot plate. I usually throw the spur excess back in between each pour. I read somewhere that with a bottom pour pot you may need to set alloy temp up to 850 degrees. Can you give me some pointers? Or critique my process?
