Do as I say, not as I do. :: :: ::
I started on a Flintlock and then bought some caplocks.
The caplock is simple, reliable (if you set the hammer on half cock while raming the ball) and the ignition is about as fast as a cartridge gun.
With a Caplock, there are no flints to set, change, or knap. No frizzens to wipe, pans to prime, vent holes to pick, flashes of exploding powder right in front of your shooting eye, flashes in the pan, no flashes in the pan, small burning sparks falling on your balding forhead...
While the guy on your left pummels you with brass from his AK47, you Flintlock shooters need to worry about things like the Blond sitting on your right, and the possibility of setting her ratted hair on fire....
In other words, it's just a lot easier for Caplock shooters to concentrate on the basics.
You know: measure the powder into a powder measure, pour it down the bore, place the greased or spit wet patch on the muzzle, place the ball on the patch and start it into the bore, ram the ball to seat it on the powder, cap the nipple, pull the hammer to full cock, aim and fire."
I obvously shoot both Flint and Cap lock guns.
If I am going to shoot just for the fun of shooting and making smoke and having people walk the length of the range just to see that strange gun fire, I usually use the Flintlocks.
If I am shooting to see how many balls I can put thru the 1 inch diameter 10 ring, I'll use the Caplock.
