An old Kit Ravenshear (now deceased) capper if I have my percussion gun, a percussion cap tin of crisco-based patch lube, a ball screw (for unloading) , a breech plug brush (for cleaning) , a cap box with spare caps, 10-15 extra balls, a small stiff brush, spare nipple pick (in strap) , loading block (in strap), a turnscrew/nipple wrench/mainspring vise combo tool I made that will fit all the screws on my rifle, a folding knife for cutting patches on the loading block, spare nipple if I'm going to be gone for a while, and a pair of hand-forged pliers. My "Day Bag" is about 8" X 10". The day horn is very small, holds about 20 charges for a .54Cal.. Hunting knife is in a sheath on the back of the bag. I wear it very high so it doesn't "flop" when walking. I also hunt with a .58 Cal. Enfield 2-band (Hey, my Confederate ancestors carried and used them; makes it "American" in my heart, anyway. Besides, they were made at Enfield on American machinery!!). I carry the regulation Federal cartridge box, sling removed, belt carry, with 20 rounds of paper cartridges, regulation musket cap box, both on a repro period belt. Combo tool in the little pouch in the front of the cartridge box. Deer fall and don't get up when the .58 Minie connects. 70Gr. FFg. charge
Sold both my .54 Cal. flint, and my .54 Cal. Green River Rifleworks Trade Rifle. Currently trying to get up enough dough up to get another flint .52 / .54. Also building a .45 Cal. sideslapper half-stock Southern Rifle, later period percussion. Campchair
