Pictures are worth 1000 words so here are 3000 words with less typing. It was easier for me to just open up my BP carry kit, pull everything out, and take a pic and post it here.
If you have any questions about what you are looking at let me know. The wood box on the upper right is my powder magazine. It holds loose powder, lead balls, caps, powder scoop, powder measure, and a wood dowel for setting caps if necessary. The powder magazine obviously doesn't fit into the tackle box. The grey plastic box is a fishing box from Walmart. It has a pull out top tray.
p.s. The sheriff's badge makes me shoot straighter.
