Track of the Wolf has added a .595" Lee two cavity mold to their product line. I understand this Lee ball size is exclusive to Track of the Wolf.

As those who follow the original data know, the loaded OAL of this roll crimped round needs to stay at, or under, 2.76" to feed reliably in many 3"chambered repeating actions. With the original 3 x .600" inch payload, this can be a tight fit for OAL.
Using a .595" ball will trim approximately .015" off of the stack height and resulting loaded OAL.
