It takes all kinds even in the reenactment world. You got three basic kinds; historians, competitors and party people. There is very little blending between the groups, though the competitors will often sit and have a cool one with you should they know you and not have a rifle in heir hands at the moment. (they tend to be on the safty conscious side). The battle boys will on occasion kick up their heels if it is a scheduled and planned activity and they know who is in charge. (they are very organized and disciplined)
The party people come to get blind running drunk. That is their goal and they do it very well! Some of them own Muzzle loaders, but their real strength lies in their knowledge of how much of one brand it takes to fire them up compared to another cheap or premium brand. They may be missing a ramrod or front site or have a rust problem, but that's no sweat, there's plenty of Captain Morgan (the only officer they recognize).
The historians know everything about everything and will tell you most of it in one sitting. They know their buttons, their fabrics, the cut of their shooting bags and moccs, the sweep of their knife blades and what Herman Blundersplitz had in his pockets on June 5, 1684. They have sone nice guns, rifle and smoothbore, and some of the scouts will know where they hit, but on the average they consider the guns part of the decorations, not working tools.
Oddly, most of the battle people I have met through the years are liberals and have some funny ideas about gun control. There are exceptions, (espically the frontier people) but most never make the connection between the decoration they use for drill and a "real gun". Of course that is one of the same problems that the commanders had with the militia and most of the regular units during any major conflict during the BP era. They didn't realize their muskets were for firing and seemed really suprised when the enemy started throwing chunks of lead their way. American militia were the second fastest soldiers on Earth. (the fastest were the Egyptian tankers driving in reverse during the 6 day war)
The competitors are just that. They go to rondys to see their friends and shoot. Usually they will be historically accurate enough to not get thrown out, but they do not go to events where there is no shooting. Usually they do not stand around pozing for pictures with that far away gaze on their faces, arms resting on the muzzle of the gun, hat pulled low or removed to show the long hair.
The competitors may not know all the history in the world, but they know the range schedule and who the best shooter at the event is before the first round is fired (they are praying he will have a bad day or they are shooting for second place from the start). Competitors' camps can usually be spotted at a distance due to the presence of multiple rifle stands and large boxes of cleaning gear. Newbies can recognize these camps from the markings on the boxes, they have big letters that say GUN STUFF.
As a rule, the competitors do not go to nonshooting events. The battle reenactors go places to fire only blanks (they actually consider this live fire and get mad it they don't get to shoot several rounds off during a battle). The party people usually do not remember if they put the gun in the truck and they stepped on their powder horn at the last party so it don't really matter, never can remember what caliber that thing is!
You'll find an old timer that shoots and knows some history now and then. Occasionally you will run into a frontier scout who knows exactly what charge his powder measure holds and what patching his rifle likes best. Once in a while one of the party people will sober up and do a flint and steel demonstration for the school kids. There is some flow between the groups, but you can usually walk through an event and spot the types.
Often you can label the whole event one way or the other as soon as you walk into camp and look at the range. Historic sites usually do not have a range, they are there to educate folks. The party people have a "spot over there where you can shoot" if you remembered the powder and the gun has a front sight. Competition events will have several ranges laid out for different purposes, safty officers and all the trappings such activities require.
There are exceptions,
others; milage may vary.
