flints, special tools, patches, etc, or a lb .22 unit and 1500 rds of .22lr ammo? Personally, with a scope and can on the CAR, trigger job, etc, I can make 1500 rds of .22 feed me for 50 years. Since the muzzleloader is at LEAST 8 lbs, more like 10, usually, you dont GET many shots out of the remaining 1-3 lbs of powder and shot. Figuring 1 lb of patches, special tools, powder horn, etc. at 7000 grs in a lb, 70 grs per loading, that's a lousy 100 shots. You AINT gonna make decent FIREARM use black powder. The "corning" of the grains is REALLY dangerous. A 180 grs or so to the ball, you don't get a lot of balls out of a lb of lead, either. Not that lead is all THAT easy to locate, mine, etc.
Muzzleloader is a LITTLE KID'S idea of survival gear. WORSE than bow and arrow,even.
