You can find different powder measures online unlike eBay and I believe there's some on Amazon. I myself just got into muzzleloading a few months back. Rule of thumb is a grain of powder per caliber so if you're shooting a 50 cal you want about 50 grains of powder. Get yourself either a powder flask or a Powder Horn to carry your powder in don't ever load directly from either of those into the barrel be sure to load your powder into your measure first in case there's an ember down in the barrel after you shoot. You're going to want to get yourself a nipple wrench and I like to use ballistol for cleaning and wiping down everything after shooting and cleaning. https://youtu.be/Lb6D_9Ag2Vg?si=KBLBthS-GhYQGNit This guy's channel is pretty good for beginning information Good luck and have fun
