Yes, Selous beginning in 1871 through about 1881. He used a 4 bore loaded with a 1750 gr lead round ball over about 410 gr of coarse grade BP. He later lamented ever using that gun as he swore the recoil ruined his shooting ability because of the recoil. His tracker once double charged it just before shooting an elephant with the resulting recoil causing severe lacerations and breaking the stock. This info is from: A Hunter’s Wanderings In Africa by Selous, pgs 73 & 111.
Rule #1 in Loading/Reloading a Muzzleloader: Never, Never, let someone reload your firearm without supervision. And if such intent is for the owner to fire such loaded firearm.
Rule #1 at the range: Never, Never allow yourself to be so distracted to not finishing loading/reloaded your muzzleloader that you; double load or charge, forget to powder charge and seat your projectile, or leaving in and firing your ramrod out the barrel.
However, It is okay to teach someone the skills in loading/reloading a muzzleloader and to let them, once they become somewhat skilled in the use of the muzzleloader, to be afforded the shooting experience while being observed at a comfortable reactionary distance. If they do something inappropriate they can be stopped and questioned before anything goes wrong. Or they can learn from a bad experience, not to have that same "brain fart" in the future.
Okay, I'm going to say no further violations of the various Rule #1's in loading, shooting, handling, safety, maintenance, etc, of side lock muzzleloaders need any further discussions or examples.
I don't think one can carry black powder or substitutes on an airplane. So, that would have to be sourced locally.
Correct.
Black Powder and substitutes are considered explosives.
Not sure, possibly in the "gray" area, but caps and primers could also be considered explosives, as these are also hazmat items.
Check with
@Gert Odendaal and your outfitter/PH if they can locally source these items. Especially with
@Gert Odendaal for the best/better quality local brands.
