After reading the book by Veral Smith, I bought his mold for 32 winchester special. "LBT molds".
Slug your bore and slug your chamber first. I found many of the "production" company molds were too small in diameter for my gun with cast bullets. That being said, I would go custom from Accurate, LBT, Mountain molds, etc. Mine is .323 diameter. Ya I paid a premium, but I can't stand spending money on stuff that doesn't work the first time. There are enough challenges from what I have read. I am new to this and am looking for success, not headaches.
