Thanks for all the responses... But it leaves me wondering why the flintlock was replaced by a system that didn't perform significantly better.
Caplocks worked better when flash paths were properly maintained and good quality caps were available. The locks are simpler, faster ignition is possible, and the cap is now called a primer in the brass hickey thingamajig.
But the usage of Flintlocks spanned a much greater time, they are not so fussy to keep working properly, and ANY dry powder can be used to prime the pan. It matters not what happened to your supply of caps. One must have powder to load his gun, and a little tad more to fire it (FL). One can have a keg of powder and be SOL with a caplock.
As I see it ultimate hard-times functionality of a well-known design is what stretched FL popularity well past the "expiration date" in the woods and cabins of America (and other lands I'm sure). There may have been some old-timers who trusted their dusty old mules over the new "trick pony".
Also, put a little "mother nature" into the shooting events and FL take no second seat to Cappers. Shooting skills once again become most important, not lock time. I witnessed this just a few years ago at a blustery chunk event. FL's ruled.
