Years ago--early '90s maybe--Doc Carlson wrote a product review about a matchlock, and mentioned hunting with it.  I ran into him a few months later and we briefly discussed it, turned out he was hunting from a stand.  I had to give it a try so I built a matchlock, and was out with it that fall.  Problem is I'm a still-hunter.  
Managing the match was a headache.  I was checking it every few minutes to make sure it hadn't gone out or burned down too far.  A couple times the free end managed to get tangled in brush.  I was using a nitrated hemp/cotton cord that burned at a fairly fast rate (we know today that a bucked hemp cord soaked in lead acetate burns slower and hotter).
I hunted into the wind.  If any deer noticed the smell of the burning match it didn't seem to bother them.  A couple times I stalked within ~25'.  I filled my tag and as best I recall didn't shoot the gun again before I traded it off.
