Here's a picture of contents though some come or go depending on flint or percussion and expected weather.
From left to right:
1. Short Starter
2. Hunting knife (which one varies by game type)
3. A capper if hunting w/percussion, or a ring with pick, primer, and pan brush for flintlock
4. Flask for main charge powder w/measure
5. Hunting License
6. CO2 discharger with appropriate tip for type of ignition. Saves your bacon if powder gets wet and you have to blow the charge out. Much much faster and safer than pulling the load.
7. Ammunition.
8. A cow's knee if wet weather is expected
9. A flint-kit if taking the rock-lock. Has a few extra flints, a knapping hammer, a driver for the cock-jaw screw, and another pick that's much thinner (actually carry the pick as well if using caplock)
10. My possibles bag can also accommodate a small lunch and I usually have a small baggie with a few pieces of towel paper and some cleaning patches (dry...I just pour a little water from the canteen I carry when I need any of them wet).
