I can't find any posts that address this so I will start one! I have just purchased a Lube A Matic 2 and have a top punch to do flat top boolits. No issues there. But I like the 520 gr. .458 45-70 boolits for my Shiloh and Pedersoli rifles. Both the 500 and 520 gr. boolits work great in both guns. I can't seem to find a top punch with a rounded punch top to fit the 520 gr. boolits. What do you folks use to size and lube these rounds? I like the consistancy that swaging and lubing the rounds when run through the Lube A Matic. Does anyone know of a source for a top punch to be used with a round top boolit? I don't want to deform the rounds when I run them. The Shiloh Sharps is very sensitive to any deformation of the round nose rounds.
