I am new to this forum and this is my first post.
I have this mold that I likely bought in the early 90's.
I mostly cast for muzzleloaders, as that is most of the molds I have. Of all my molds this is one I cannot identify.
It appears to be some type of Maxi-Ball.
All I know is that from my caliper measurements is that it is a .54 cal.
Only Markings on it is the number 948 as seen in the pic.
By the weight and looks it is steel and not aluminum.
I have searched the number on the mold with no luck.
Thank You
Steve
