Powder Horns.

Nice horn.
I have one but not as nice as yourn.

 

@Keith H
This may sound like a stupid question but why a horn instead of a leather pouch as u keep ur extra power in leather wallets in ur knapsack
I hav no real experience with firearms and only used horn to make glue or bowls and if a nice big one then for drinking mead

I've kept my maternal grandfather's powder horn. As a young man (way past poor he was) all he had was a muzzle-loading .32 percussion cap rifle. I appreciate today's finer-than-fine rifles because my kin didn't have diddly. The powder horn is a reminder to be thankful for all that I have (food firearms fuel) and to keep my departed kin in my prayers (don't know when you'll need them prayin for you).

 

I had a old 36 Cal Flint lock but I give it to a young boy that did not have a way to hunt and was really wanting to hunt with black powder so I gave him the Flint lock and a 36 Cal mould and the hunters frock that I am wearing in the picture the boy now a young man still uses that Flint lock

 

In the USA, muzzle loading weapons do not have any paperwork associated with them. If one wishes to stay off the Big Brother paperwork grid, he or she can go buy a cap'n'ball revolver. They are a trouble to feed'n'fire and to clean up after going to the range, however they are beautiful, the recoil isn't sharp, and the big bores are as deadly as all get-out. The old Colt Walker sure was a killer.

Here's a bunch of ballistics tables for black powder weapons / loads. Scroll down to the .44 Colt Walker using conical bullets. These boys launch with over 400 ft-lb.s of energy -- enough said.

Remember to use a wax-grease / lubricant forward of the ball to prevent chain-fire -- same around the primers at the back of the cylinder.

One can make paper cartridges topped with conical bullets for these revolvers. Here's a Google search result for instruction videos showing you how to make your own:

I guess if you get good at turning out these home-rolled paper cartridges, you could save a bunch of money.

 

It is true at the federal level muzzleloaders are not "firearms" as far as the ATF is concerned. Not, however, there are some strange and/or Draconian state-level regulations concerning front-stuffers in some areas. Anyway, it pays to do a little research on the topic to avoid any trouble with the state and local statutes.
