A friend of mines father passed away recently, a caster and avid long range BP shooter from Lincoln, NE. He knew I cast so he brought me the moulds. I didn't recognize them at first but after some closer inspection they are five Lee .45 caliber 2 cav moulds reamed out to .484 and marked accordingly. I am very unfamiliar with BP guns especially something as odd as this. What caliber is this? Any help appreciated. Tks Clinton.
