I just picked up an original Mississippi .54 (4th Model Harpers Ferry Conversion).. The bore measures out at .526. (micrometer and slugging barrel) I have a Lyman 54 Cal Minie mold that throws a .533 bullet. Is that to large to size down to a .525?? I really want to shoot it with a Minie if possible.
I notice that rifling is deep. I suspect a hefty charge is needed to expand that skirt to make it shoot accurately.
Thanks in advance for any input..
