Fourth Of July Groundhog

Went groundhog hunting on the 4th of July with my brother. My brother took a .22 rifle and I my flintlock. We found a groundhog and got within 25 yards of it; the plan was for me to fire then my brother was to fire after me in case I missed. Well, I got my fiber optic sights lined up on it and fired. Promptly I heard click…crack then the groundhog fell over. My my brother did not waste any time before shooting after my misfire! We did not see any other groundhogs that hunt, but we had a great hunt.
