I have a Paul Jones mold I had made for my Austin Halleck .50 cal inline M/L it is 500gr FN that cast a .500" bullet with near pure lead( a little tin added).This bullet is exactly bore dia. I want to make the bullet .002 larger so it engages the rifling and stays put while hunting.This bullet shoots amazingly well with 80grs. of Swiss 1.5 but is just a bit to loose for hunting.
What is the best way to get the bullet bigger,should I send the mold back to P.J and ask if he could enlarge it? Is "lapping" a viable option?
