Got 2 Lyman 4 Cav molds at a gun show today.
Thay are marked 452460 kw an 452460 cn.
What does the kw an cn mean ???
Thanks

I am fairly sure they denote the cherries used to cut each mold cavity with.

yep cherry and maker code.

Cast them both and maybe you can tell us.

Codes to distinguish between all the other #452460 cherries. When one cherry starts to wear out and needs to be replaced they can say which #452460 needs to be pulled.

Cast with both. Don't be surprised of the two are a trifle different. Lyman has been known to tweak mold designs over the years.
