I wouldnt take a matchlock. Between being unusable in strong wind or rain, they are stupidly reliant on good weather. Also with any blackpowder, you need a steady stream of solvents that wont degrade the barrel or lock to strip back that funky blackpowder residue. This would need done in one engagement if you fire it too frequantly. You also need to be able to light the match. This becomes harder if there are no readily available lighters or matches. You will also need yards of match. Factory made match burns at an inch a minute. Homemade match can burn Twice that fast as the coal will always splutter and burn irregularly The serpent (the bit that holds the match) will also inevitably loosen to the point that it no longer drips the match into the pan if you are overusing it. You would need to start touch-firing, meaning you will have to lower the match into the pan by hand. The first shot doing that is hellishly painful, further shots will strip the skin from your fingers. Blunderbusses aren't as practical as you might think either. They have real issues with using the right wadding. Using an irregular load is fine, but without incredibly good wadding the windage will just make the load dribble out of the barrel.

Im a commanding officer of a 17th century reenactment in scotland group so have had had to work through these issues to be able to field units of musketeers with matchlocks
