Again, it’s been a while. Partial explanation towards the end of this post.
So, the BBTI team finally got together to do something we’ve been wanting to do for several years now: shoot a Gatling Gun. Yep, a real, honest-to-gawd Gatling Gun. Well, not an original, but a faithful reproduction of the original 1862 patent version, in .45 Colt. This one:
It’s such an iconic weapon, having been used around the world for about 50 years (from the American Civil War until World War One). And almost anyone who has seen Westerns has probably seen one depicted on the screen. So when the opportunity presented itself to get a fine reproduction one at a reasonable cost, we jumped on it. And last weekend we were finally able to coordinate our schedules to get out to shoot the thing.
But first we had to assemble it, because it breaks down into several components for ease of transport and use. Overall, the whole thing weighs more than 300 pounds. The main element is the barrel & mechanism assembly:
We’ve got a nice tripod to mount and shoot the gun. Here we are assembling that:
On top of the tripod is a pivoting mount, so you can rotate the gun from side to side. Into that goes a yoke mount, to which the gun is secured. Elevation is controlled by an adjustable wheel screw at the back.
The way the gun works (the Wikipedia entry is pretty good, as well) is that you put the cartridges into machined sections of heavy steel tube called a ‘chamber’ (essentially, a section of barrel), and those are placed in a magazine. The magazine goes into the top of the gun, upside down. Each chamber drops into position behind a barrel, then is pressed forward and locked in place as it rotates to the next position. The barrel then rotates again into the firing position, a firing pin ignites the cartridge, and the bullet fires. As the barrel rotates again, the chamber is released, and falls free out the bottom of the gun. This process is repeated for each barrel in turn as long as you turn the crank and there are chambers in the magazine.
Here you can see a test run with empty chambers to make sure everything feeds and falls properly:
Next, we wanted to make sure that the firing pins were working properly:
After that, it was time to load ammo and give it a try.
I’d loaded 1000 rounds of .45 Colt, using 200gr lead bullets and 6.1gr of Titegroup powder. This is a mild handgun load, but we weren’t looking for a lot of power, just a lot of fun. Still, out of the 30″ barrels we were probably getting about 1,000fps and roughly 450ft-lbs of muzzle energy — a respectable amount of power.
Here’s Keith of the BBTI team giving the Gatling Gun its first live-fire trial;
Yay! It worked!
Soon, I got my turn:
Dude, that’s way cool.
OK, several things we discovered in shooting the Gatling Gun …
One, you quickly realize that once you start turning the crank, you find there’s an optimal speed where it feels easy and consistent. I got there at the end of the video above.
Two, you can go through the 44 rounds that our magazines hold in about 20 seconds when you know what you’re doing.
Three, it helps to have someone actually hold the magazine in position, rather than relying on the small set-screw to hold it.
Four, the gun is surprisingly accurate and consistent. Once we got the hang of it, at 20 yards (the effective distance we had to shoot it), we were all getting paper-plate sized groups. Like this:
Seriously, I was very surprised by this. I expected something more like “minute of cow”. I look forward to shooting it sometime at longer ranges to see just how good you can get with such a gun.
After we all had fun shooting the modern ammo, it was time to try the gun with black powder cartridges. Specifically, 30gr of Goex FFg and the same 200gr lead bullet. I shoot a fair amount of black powder, and know that it can be messy … but man, it was an incredible mess in the Gatling Gun. But it sure was spectacular. Check out the long tongues of flame from this sucker:
And just think about what a battlefield with a bunch of those cranking out rounds would have been like. Blimey.
Now that we’ve finally had a chance to get together for an inaugural shoot of the Gatling, it’s something that each of us is going to take for a while, and share with friends. Look for more coverage of it in the future.
So, what was that about Laser Pistols, and why have I been so absent/quiet here for so long?
Well, about a year and a half ago I got a Glowforge laser cutter, which I mentioned in passing in my post last November. I kinda fell into a deep hole playing with it since then. But it’s all good, because one of the things I have been doing with it is making a whole bunch of handgun display models/art, like this:
That’s one of the 42 contemporary designs I’ve done. I’ve also done a bunch of historical firearms, such as the 1851 Colt Navy Revolver:
And even favorites from various Science Fiction franchises …
The whole thing can be found here: Art of the Gun and I invite you to stop in, check it out, see the many different designs I’ve come up with so far. I’ve just launched the site, but already it is starting to get some positive feedback — so maybe you’ll find something you like there as well.
One last thing: we’re not done with the BBTI project. Something else we did this past weekend was to start talking about future projects related to our ongoing research. It’s too early to say too much, but rest assured that we have more work yet to do, more data yet to gather and share.
Thanks for coming by, and for your ongoing support.
