Not really. I have a bag for each muzzleloader. The one below is for my flint rifle. I refill it when I get home and it's always ready to go.
I carry a tool roll with:
Screwdriver to fit flint jaw and sideplate
Mainspring vise
Spare vent picks
12 cleaning patches
5 spare flints
Cleaning jag
Ted Cash oil bottle
Piece of leather strap (for added grip in pulling a stuck rod or ball)
I carry a tin of Moose Snot, a bottle of moose milk, a tiny (nitro tablets) of 91% alcohol to wipe the frizzen, and a waxed deerskin bag with six feet of pre-lubed cotton ticking. I also have a folding knife in the bag.
In the patchbox are a tow worm, ball pulling screw, button jag and a spare flint (wrapped in cotton tick that's pinned by the box spring so they don't rattle or fall out if the box gets accidently opened).
On the horn strap are a powder measure, vent pick (bent to hang beside the measure), and a three-hole ball block.
I also have three spare flint leathers in the ball bag (which holds up to 60 balls, but usually less). On the back of the pouch is a sheath that holds a five hole ball-block. Attached to that block with a leather lace is a 1" stub starter which is tucked into the pouch.
I make the distinction between a "possibles bag" and a "shot bag" (or hunting pouch). A possibles bag is more like the haversack. Things you
might possibly need. The shot pouch is things you WILL need to shoot and maintain the gun. Food, spare socks, cookware - not in the shot bag.
My hunting pouch is fairly small, but I can still hold the fixins for 60 rounds when treking or wandering off to shoot. And, the gear to clean the rifle up afterwards.
Carrying the same things hunting, target shooting, plinking, etc. means I don't need a checklist, and packing light means I don't need a range box. I just have to remember to put my ear plugs and a roll of masking tape in my pocket and grab some targets if I'm heading out to target shoot. I also carry a roll of cleaning cotton for wiping and cleaning if I'm planning on shooting a lot. For those days I have a canvas gas-mask pouch with a spare bag of balls,, a large tin of lube, a roll of cotton tick patching and a roll of cleaning cotton, a broadhead file, a brass/nylon drift punch, a 2# piece of lead (diver's weight) for drifting the sights, a tin of thumbtacks and a roll of masking tape to hang targets. That's my "range box".
