I took a deer on Friday and reloaded immediatly. Did not need the second shot. Since I was using Blackhorn and I knew I would hunt again in a few days I just left it loaded at the end of the day (minus primer).
Two days later I hunted again but with no luck. I got nervous leaving the ML loaded with one shot (already fired so I did shoot a tree before I left the woods the second day. Don't know if I needed to waste the bullet (FPB) and powder but figured better safe than sorry.
