I once talked to an 1812 reenactor who told me they aimed just in front of the feet of the other side, you had to be way too close to even fire for it to be visible to the audience. They tested it on a gravel parking lot and were not able to get anything to fly up in any range that didn't cause the powder to fall out before they could pull the trigger. I have thought that it would be worth testing in volley fire with .58 muskets and heavy charges, hang up some sheets and see what happens. It would if it works look better than duck hunting.
Glad you asked that question! It is vital to the core of the hobby!
Fill that rusty canteen with apple cider vinegar, cork it, and leave it in the back of a cool, dark, closet for 16 weeks. That will fix everything.
Glad to be of service!
1. All guns are always loaded.
2. Never point at anything you are not willing to kill.
3. Keep your finger off the trigger until your sights are on target.
4. Be sure of your target and what is beyond it.
