Ballistics by the inch

Spinning wheel got to go round.*

I was surprised when one of the other BBTI guys said that he had found a reproduction wheellock on Gunbroker recently, and that it wasn’t even horribly expensive. This one:

20200822_092520

Wheellock with Diablo double-barrel pistol.

I was surprised, because there aren’t many reproduction wheellocks out there that I was aware of. It’s a quirky firearm design from the 16th century (Ian from Forgotten Weapons has an excellent primer on Wheellock history and operation in this video), which was superseded by reliable & cheaper flintlocks, and not too many people are familiar with them. But it seems that a firm by the name of Mendi was producing them in Spain in the 1980s. This one is stamped along the top of the barrel “Jacobi Iserlohn”, which is a firm selling historical firearms in Iserlohn, Germany. You might be able to make out the stamp in this image:

20200822_100933

Jacobi Iserlohn.

We didn’t know much about the gun beyond what was stamped on it — it came with no paperwork or anything (which, being black powder, it didn’t need).  As you can see in the image above, it says that it is “CAL 45”, and a normal .451 lead ball seemed to fit, so …

So we figured we’d try and figure it out and shoot it, of course. The first thing was to check the bore, see if the mechanism worked, etc. Most things checked out fine, though it looked like someone had substituted welding rods clamped between a piece of thick lead sheet for the historical pyrite used to generate sparks. See for yourself:

20200822_111309

Welding rod?

Which would clamp in this (called the ‘dog’):

20200822_111313(0)

We adjusted the rods so they were equal length and extended far enough to engage the spinning wheel of the mechanism when the dog was lowered. So far, so good.

Next was to test the wheel mechanism. The way a wheellock works is that there’s a spring inside the stock, attached to the inside of the wheel usually by a chain or strap. Using a suitable crank (we didn’t have one that came with the gun, so we used a simple adjustable wrench), you crank the wheel until a ratchet inside locks it into place. We discovered that this gun only needed to be cranked about half a turn before the ratchet clicked. When you pull the trigger the ratchet is released, and the wheel spins.

We tried that, and it seemed to work.

OK, time to load the thing. We elected to start with a mild load typical for other black powder handguns we have in .44/.45 — 30gr of fffg. The lead ball seemed to fit tightly enough into the bore that we went without a patch. All of that went smoothly.

Last was to put some powder in the pan and see if we could shoot it. First, we cranked the wheel into place. Then we put some powder beside where the wheel was, next to the touch-hole. And gave it a try:

Remember, we had no idea what to expect.

At least we got sparks. Just sparks. The powder in the pan failed to ignite. We considered the matter, and decided that we had been too stingy with the powder, that it needed to more or less fill the pan all around where the wheel protruded.

The result:

Excellent! It fired! It hit the target! It didn’t blow up and kill us! Yay!

So each of us had a go:

That last one’s me. And let me share what it felt like.

Mostly, like shooting any similarly sized/powerful black powder handgun, with the gentle push of black powder. But when you pulled the trigger, you could feel a little bit of torque as the wheel released and spun for a moment. It was different than either a flintlock or cap & ball handgun, in that regard. And the delay between pulling the trigger and ignition was about what it’s like with a flintlock, perhaps a little longer.

All in all, it was pretty cool. And it wasn’t something I expected to ever have a chance to actually try, since most of the wheellocks I was aware of were either 300+ year antiques or fairly high-end (and rare) custom reproductions. Needless to say, if you do get a chance to try one of these things, definitely do it.

Review: Diablo 12ga double barrel pistol.

Want some fun? Get an American Gun Craft 12ga double-barrel pistol.

Want a serious self/home defense gun? Get something else.

Oops. I gave away my review’s conclusion. But you should go ahead and read the rest of this, anyway.

* * *

When one of my friends sent me a link about the new American Gun Craft 12ga double-barrel pistol, I thought it looked like a lot of fun. A lot of people thought so, and the cool little pistol got a lot of attention.

For good reason. It looked well made, well designed, and easy to use.

And it is. Check it out:

Diablo 1

Diablo 12ga

And this is what it looks like in the hand:

Diablo 2

Seriously, this is a very high-quality gun. It’s very solidly made. The fit & finish is impressive. The bluing is rich, deep, and lovely. The rosewood handles fit perfectly, and are warm & comfortable in the hand. They’re polished so highly I at first thought that they were plastic. The trigger is smooth, crisp, and much better than I expected.

The design is simple, but there are little things about it that are quite nice. Such as when the gun is broken open, you can rest it on any flat surface with the barrels pointing up, and it is perfectly stable for loading. If you’re shooting by yourself, this would be very handy.

Since we didn’t know what to expect, we went with the manufacturer’s recommended load of black powder to start with.  That’s just 40gr of ffg, with a recommended half ounce of shot. But all we had to shoot out of the gun were 12ga balls (.69 cal ball, about 500gr — say 1.2 ounce). So we expected it to be mild shooting.

It was:

 

Well, according to this video, that’s probably just about 250fps, and maybe 70ft/lbs of energy. That’s about the same power as a low-performing .22 round out of a 6″ barrel. And it felt like it.

So, since the amount of lead we were shooting was more than double the recommended amount, we doubled the amount of black powder, to 80gr of ffg. Here’s that:

 

Well, again according to this video, that’s probably about 560fps, and maybe 340ft/lbs of energy. That’s about the same power as a typical 9mm round out of a 6″ barrel. And it felt like it. There was a bit of recoil out of the heavy pistol, but it wasn’t at all hard to manage.

Given how well the gun was made, and the mildness of the first shots, we didn’t have any qualms about increasing the amount of powder to double what was recommended. And that was a fun load to shoot. Others have pushed that boundary MUCH further, as you’ll see in either this video (referenced above) or this very long review. By using much bigger loads and different types of powder, it is possible to get up to energy levels in the range of a .357 or even .44mag out of a 6″ barrel.

So yes, it would be a pretty reliable self/home defense gun, in those terms. And we were shooting it at applicable ranges for that use, with adequate accuracy.

But consider several factors here. First, black powder is very hygroscopic: it sucks up moisture out of the air. That can be a problem with a muzzle-loading gun, and was the reason why Old West gunfighters would commonly shoot off their loads each morning and load their pistols fresh. Because wet powder can underperfom very badly. So you wouldn’t want to load the Diablo and then just set it aside for future use.

Black powder is also a slow-burning and very smoky powder. Shooting it indoors would fill the room with very acrid smoke, and may very well spew burning bits of powder out into the room, causing fires.

Lastly, while the Diablo is indeed easy to load and shoot for a black powder gun, that still takes a hell of a lot more time than it would take to load two additional cartridges into a derringer. And almost every common modern self/home defense gun offers more rounds for use than a derringer.

So we’re back to what I said at the start:

Want some fun? Get an American Gun Craft 12ga double-barrel pistol.

Want a serious self/home defense gun? Get something else.

Much more black powder fun!

20161021_143856

A couple of summers ago, I got together with some friends and we did a little black powder shooting. Well, since then we’ve talked about getting together again with even more great historical guns (reproductions) and another shooting buddy, and this past weekend we did just that.

Did I say more guns? Why, yes, I did:

20161022_093038

20161022_094559

Total of 21 shown, with one extra hiding in that brown case in the second pic.

I’m not going to try and give a real review of every one, but using the two pics above I will identify each gun, maybe add another pic or two of it in action, and provide some initial impressions of shooting it. So, without further ado, starting with the top image:

Top gun: Early Matchlock Caliver. .62 ball, 60gr FFg. A pleasure to shoot. This felt less bulky than the earlier guns, but you had to be careful to position the thin upper buttstock such that it was against the bicep, rather than tucked into your shoulder as with a modern style of gun. The lighter weight did make the recoil more noticeable.

calivercaliver2

Below that: Swedish Snaplock. .77 ball, 60gr FFg.  Very similar to the Caliver in how it felt, though the mechanism is a type of flintlock. The larger ball would have probably benefited from more powder (the rule of thumb is about 1gr of powder per point of caliber, to start with), but it still had no problems penetrating the 3/4″ plywood at about 15 yards.

Under the Snaplock are three small Pedersoli handguns:

  1. Derringer Rider (Hardened). Uses just a #11 percussion cap to shoot a 4.5BB (standard .177 round ball). We couldn’t get this one to shoot — after the first shot, the BB was stuck in the barrel.
  2. Derringer Guardian. Uses just a 209 primer to shoot a 4.5BB (standard .177 round ball).  This one shot fine, and was a fun little gun. Trying to hit anything at more than arm’s length was a challenge …
  3. Derringer Liegi. This uses a percussion cap and 10gr of FFFg powder to shoot a .451 ball. The trigger is retracted until the hammer is drawn to full cock. This was actually a lot of fun to shoot, and had a respectable amount of power behind it. At about 5 yards it shot about a yard high from what you initially expected, but with a little practice …

Some pics of the Guardian and Liegi being shot:

20161022_100528liegi

To the right of the Pedersoli handguns is a Hand Mortar. This has a .75 chamber with a 2.5″ bore. Which, it so happens, is perfect for shooting a tennis ball …
mortar1mortar2mortar3mortar4mortar5Keith shot the first ball at our plywood target, using 75gr of FFg. The tennis ball bounced right back at us. So we reused it, this time increasing the load to 100gr of FFg, shooting it into an adjacent field. It lobbed about 60 yards. The last shot was with 120gr of FFg, and that sent the tennis ball 75+ yards. I expect that if you stuffed some wadding or such down into the .75 chamber, and tamped it appropriately, that you’d get much better performance. But we were laughing too much to think of trying that at the time.

Under the Mortar is a LeMat Cavalry revolver. The 9 chambers are .44, and we used a .451 ball with 40gr of FFFg for each. The center chamber can also shoot a 20ga shot load, but we decided not to fuss with that. We used the recommended #11 percussion caps, but #10 would have fit better. This gun was new, but the trigger was *extremely* hard to pull and cocking the hammer almost took two hands. It would probably benefit from a fluff & buff … but I don’t think I’ll run out to buy one to try it.

To the left of the LeMat is an Early Matchlock Arquebus.  .58 ball, 60gr FFg. Surprisingly easy to shoot, and reliable under the pleasant autumn conditions we had. All of us found it easy to hit close to point of aim, even with the significant delay you have with a matchlock.

arqarq2

Below that: a Kentucky Flintlock Rifle. .50 (we used a .490 ball) with 60gr of FFg. This is the iconic flintlock for most people, and felt & shot well. Though curiously, the delay from ignition of the pan to the rifle firing seemed long to me, compared to my Mortimer (see below).

ken-flintlockken-flintlock

Moving to the second image of guns at the top of the post …

Starting at the top, on the left side of the image: simple Hand Gonne in brass. .62 ball with 60gr Fg. After pouring in the powder, you just drop the ball in without a patch … and have to pay attention that you don’t let it roll out again. We started the day shooting this, and all had entirely too much fun. Initially we used 40gr of Fg, and were able to pick up and reuse the ball, since it just bounced off the plywood target.

gonne2

Below the Hand Gonne is my 1815 Mortimer flintlock. .535 ball with 60-80gr of FFg. I’ve written about this gun previously for my personal blog, and really enjoy shooting it. Even with the more powerful loads, there’s very little recoil … because the damned thing weighes a ton! But it is well broken in, shoots very well, and is accurate in my hands to at least 100 yards.

Under that is my new 1858 Remington Revolving Carbine. .454 ball with 30gr of FFFg. This was my first outing with this gun, and I just love it. We all were able to shoot about 4″ groups at 15 yards the first time. With a little practice, I am sure I can extend that considerably. Here’s  a couple of images of it from this weekend:

185818582And some video:

Under that is a French Blunderbuss. .735 ball with 60gr Fg. This was the first time any of us had shot one of these muskets, and we were all pleasantly surprised at how accurate and reliable it is. I can now understand why it was considered such a valuable weapon for close combat.

blunderblunder2

Next down is the Kentucky Percussion Rifle. .50 (we used a .490 ball) with 60gr of FFg. This is the twin to the iconic flintlock up above, and shot nearly identically … except that the #11 percussion cap gave immediate ignition to the charge. A very nice shooting rifle.

ken-percussion

Next to last on the left side of the second image is a Japanese Matchlock. .50 (we used a .490 ball) with 60gr of FFg. I had shot this one previously, but it was fun to revisit it and compare it to the other matchlocks we had. All of us found it easy and accurate to shoot.

japanese

At the bottom on the left is a 1766 Charleville musket. .68 ball with 80 grains of FFg. This gun had probably the longest delay of any of the flintlocks we shot, but was still very fun to shoot, went off reliably, and seemed very accurate.

On the top of the right side of the second collection of guns is another 209 primer only 4.5BB carbine: the White Hawk. This was *surprisingly* fun to shoot! It was easy to use, accurate, and the .177 pellet seemed to hit with more authority than you would expect, though we didn’t test it for power. All of us had to try this several time. I could really see this being a fun little thing to shoot in your basement or some such.

20161022_1014160

Below the White Hawk is a Howdah Hunter: a twin-barrel .50 percussion cap gun which we loaded using a .490 ball with 30gr of FFFg. While heavy and with a stiff pair of triggers (one for each barrel), this was easy to shoot than I expected. Recoil wasn’t bad, and accuracy was good.

howda

Under the Howdah, hidden (unintentionally) in the gun case, is a home-made Hakenbushe (hook gun), a variation on the early hand gonne which had a ‘handle’ that was a steel spike, used for close defensive work after the gun had been fired. This one shot a .735 ball with 60gr of FFg, and like the other hand gonne above, didn’t use a patch. So you had to make sure not to tilt the barrel down, or the ball and powder would roll out.

hookhook2

Under that is a classic Hawken rifle. .50 call (.490 ball) with 60gr of FFg. This may be more popular than even the Kentucky long rifle, and it was a fun old friend to revisit.

hawken

Lastly, two nice flintlock pistols, only one of which we were able to actually shoot. That was the 1763 Charleville pistol, .68 ball with 40gr FFg. A classic cavalry pistol which was very easy to shoot.

20161022_135752

The remaining flintlock is a Murdock Scottish highland pistol .52 cal. Unfortunately this one needed to have the touch-hole reworked a bit. So perhaps we’ll get to shoot it next time …

Some black powder fun.

This past weekend I had the chance to do some black powder shooting with a couple of friends. Here’s most of the firearms we shot:

081401

From left to right: 15th century Handgonne (.75 cal), 16th century Japanese-style matchlock (.50 cal … I think), then a matched pair of smoothbore flintlocks from about 1760 (.69 cal). We also shot my 1815 Mortimer flintlock and a 1876 Hawken percussion cap rifle (.50 cal).

It was all kinds of fun. Here’s a short video of shooting the Handgonne:

 

Here’s a nice detail of the mechanism showing the match and pan on the matchlock:

081404

This clip of shooting it shows the problems inherent in having a match (the burning cord) which was actually too small:

 

Then here’s a shot of loading the Hawken:

081406

Examining it before shooting:

081405

And then shooting:

081407

And here’s a bit of video:

 

Some modern guns and short reviews of them to follow later this week.
