I mostly hunt deer and after that first shot, I always want to reload quickly even if the deer is down and in sight - sometimes they jump up and run. I liked the idea of a cartridge box but that is too much. I just need a couple of pre-rolled paper cartridges where I can get a hold of them quickly. So I decided I'd make my own hunting pouch with a 3 shot loading block.
My flint wallet will fit in the bottom along with a turnscrew/flint hammer combo and a small pouch of extra balls. extra patches go into one of the small pockets. I think this will work for me.
