This is a 45cal, 500gr cast bullet pulled from an old US Cartridge 45-70 with copper colored primer. I was surprised to find cannelure marks in the bottom of each lube groove but with no lube present. The pics are "as" pulled.
Any ideas on the casting/forming process for this bullet. Was it born smooth and the grooves created via cannelure and what are they for if not lube?

I surely do wish there was a way to correct the post Title after posting. Dang misspelling!!
