Even pirates were able to do such things back then. To precisely aim a shot at a target that is moving, one had to take into consideration the wind factor, distance, properly lead the target, etc. Many factors came into play, which is I think why a "called shot" would require a lowered AB. If the target is just standing still, the shot is made even easier.
Hitting someone in the leg or in the hand, or head from 30 feet away is not hard at all, even with a crude flintlock pistol. If the pistol was made well enough, and the barrel is rifled precisely, the shot will be fairly accurate.
Maybe, this could only be an option with the well-made Gearling brand of flintlock pistols. The cheap kind (naturally) would backfire occasionally and be rather inaccurate.
Today, snipers have precise instruments that help them calculate wind, distance and even more precise factors such as the rotation of the earth in order to make a precise shot from a ridiculous length away.
Yes, I'm sure it would require a great deal to implement. But it's certainly on my wishlist. And I think other players might like it also.
Always been intrigued by the art of sniping.
Anyone for or against this idea?
