Don't worry inlines are pretty easy. Just remember powder then bullet. If you use those pellets it's usually put two down the pipe, seat and ram the bullet down. Put the ramrod back. Open like a single shot shotgun and seat a primer in the back of the breach. When ready to fire chocolate chip cookie it, aim and squeeze the trigger nice boom lots of smoke. Theres a reason muzzle loaders are sometimes called smoke poles.
There are some things that help you stay straight about safety. Like once you get it loaded with powder and bullet leave your ramrod resting against the bullet and mark the ramrod at the end of the barrel. This way if you look at the mark every time you load you'll know if you forgot to put powder in first ( can't see the mark) or you loaded it with powder and bullet twice and now see the mark like 1.5" above the end of the barrel
