I night-hunted hogs with my .54 flinter almost every week for a year. 4 out of 5 nights a shot was not fired, so I used a ball-puller on a stainless steel range rod (with bore guide). Saved balls, tossed most into a shooting bag for offhand practice. No problem busting clays on strings offhand at 50 yards with these "pulled balls" loaded hole-side down. Killed several hogs with these re-used balls as well.
Since the powder is slightly compresses upon loading, I carefully and slowly ran ball-puller back down and loosened the powder, turned rifle bore-towards-ground, and tapped the butt end so powder would fall out. Repeated several times, then used breech scraper, then a couple of spit patches, dry patch, finally a Ballistol patch. Good to go until next week's hunt!
