Live demos test effectiveness of Revolutionary War weapons

Ars Technica: What else can we learn from these kinds of experiments?

Joel Bohy: One of the things that’s great about the archeology end of it is when we’re finding fired ammunition. I mostly volunteer with archaeologists on the Revolutionary War. One of my colleagues has worked on the Little Bighorn battlefield doing firing pin impressions, which leave a fingerprint, so he could track troopers and Native Americans across the battlefields. With [the Revolutionary War], it’s harder to do because we’re using smooth-bore guns that don’t necessarily leave a signature. But what they do leave is a caliber, and they also leave a location. We GIS all this stuff and map it, and it’s told us things about the battles that we never knew before. We just did one last August that hasn’t been released yet that changes where people thought a battle took place.

We like to combine that with our live fire studies. So when we [conduct the latter], we take a shot, then we metal detect each shot, bag it, tag it. We record all the data that we see on our musket balls that we fired so that when we’re on an archeology project, we can correlate that with what we see in the ground. We can see if it hits a tree, if it hits rocks, how close was a soldier when they fired—all based upon the deformation of the musket ball.

Ars Technica: What is the experience of shooting a replica of a musket compared to, say, a modern rifle?

Joel Bohy: It’s a lot different. When you’re firing a modern rifle, you pull the trigger and it’s very quick—a matter of milliseconds and the bullet’s downrange. With the musket, it’s similar, but it’s slower, and you can anticipate the shot. By the time the cock goes down, the flint strikes the hammer, it ignites the powder in the pan, which goes through the vent and sets off the charge—there’s a lot more time involved in that. So you can anticipate and flinch. You may not necessarily get the best shot as you would on a more modern rifle. There’s still a lot of kick, and there’s a lot more smoke because of the black powder that’s being used. With modern smokeless powder, you have very little smoke compared to the muskets.
