I never even carried the stuff he recommends when hunting. I carried very little compared to his little bag suggestion. Much of the stuff he shows stays in my truck in the backpack. Of course it depended on what I was hunting. Deer, for instance, I carried 4 or 5 balls plus the one in the rifle, lubed precut patches, powder horn, a very small priming horn. The patchbox holds an extra flint while my short starter is on my bag strap and a screwdriver tool. When hunting squirrels I carry about twice that number of balls, and when using premeasured powder I leave the horn at home. I've often hunted with no bag or horn and everything I needed in my pockets. I always thought I carried too much stuff but then, maybe not.
