I think from all these posts (thank you all very much) we can conclude that it isn't so much the type of gun that's being taught, but the person that's doing the teaching that makes the most difference. Flint guns add a measure of complication to the procedures and precautions that cap guns do not have, and each has to be manually performed. Every time you introduce a human action in to the situation that presents another opportunity for a mistake. Many / most of them do not produce an injury, but more of a frustration (failure to fire). Now when it comes to actually SHOOTING them, because of the longer barrel dwell and pan flash, they add quite a bit of extra challenge to accurate shooting. Since most Scouts shoot off the bench most of the time, that's of a lesser concern, but it is still there. Now when it comes to changing NRA's or BSA's mind on the subject regarding policy, that's a bigger challenge. FYI; according to the "No Fun Book" Scout units are NOT allowed to operate artillery pieces, though Council level events COULD use them (such as for flag ceremonies for Wood Badge). I haven't staffed a Wood Badge course yet, but if I do, I will volunteer my 1" Naval gun for use at those ceremonies.
