Bandoliers of wooden bottles with a pulvern or priming horn and a ball bag were used generally in the early 17th Century.In this post you state that cartridges were not developed until the 1700's. I beg to differ. (I assume you mean paper cartridges.) The Matchlock musket came about around 1475, or so. Very shortly after that the Musketeers were using speed loaders and paper cartridges.
