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 12ga

And this is what it looks like in the hand:

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.

Reprise — Storing Ammo Long-term: Because without Rounds, Your Gun Is Just a Poorly Designed Club

Prompted by my friends over at the Liberal Gun Club, this is another in an occasional series of revisiting some of my old articles which had been published elsewhere over the years, perhaps lightly edited or updated with my current thoughts on the topic discussed. This is an article I wrote for Guns.com, and it originally ran 8/17/2011. Some additional observations at the end.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

It’s a classic scene: Mad Max rolling a shotgun shell between his fingers, trying to see whether it is still any good.

Will it crumble? If it doesn’t, will it still fire?

Only his script-writer knows for sure.

But how much does it have to do with reality? How long will ammunition stay good, and under what storage conditions? Talk about classics – that basic question has been a standard of firearm discussions online going back to before there even was an “online”.

Whether you’ve just found an old box of shotgun shells in the back of your closet or you’re planning ahead for the Zombie Apocalypse, it’d be good to know whether you could trust those rounds to go bang when needed.

So, what’s the answer?

Well, it depends.

Chances are, if the ammunition has been made in the last century, and has been stored reasonably well, then it’ll still be good.

OK, let’s qualify, qualify, qualify that statement. Chances are, if it was a quality factory ammunition, made in the last century, and has been stored reasonably well, then it’ll still be good.

Chances are, if it was a quality factory ammunition, made in the last century using modern smokeless powder, and has been stored reasonably well, then it’ll still be good.

Chances are, if it was a quality factory ammunition, made in the last century using modern smokeless powder and with a non-corrosive primer, and has been stored reasonably well, then it’ll still be good.

Chances are, if it was a quality factory ammunition, made in the last century using modern smokeless powder and with a non-corrosive primer, and hasn’t been immersed in water or subject to prolonged sub-freezing temperature, then it’ll still be good.

Hmm. That makes it sound like there’s not a good chance, doesn’t it?

But I don’t mean to say that. The truth is, if you come across a box (or can or pallet) of ammo made after WWII, and the exterior doesn’t show signs of obvious damage or corrosion, it should be fine. I’ve shot plenty of such ammo over the years – stuff that is older than I am. And it’s likely that if the ammunition was made after the shift to non-corrosive primers in the 1920s – which covers most non-military ammunition – it’ll also be fine. In the West, even military ammunition made since WWII has predominantly been made using non-corrosive primers, and is likely very stable. Eastern bloc countries used corrosive primers until much, much later, which meant not only could they present a problem with barrel damage if the firearm wasn’t cleaned properly, but that there was a chance that the primer would become weak with age and wouldn’t completely ignite the gunpowder in the cartridge.

How about storage? I mean of ammo made recently – how should you store it to increase the chances of it staying good?

The biggest thing is to keep it from resting in water. Sounds like a no-brainer but you’d be surprised.

Some ammunition is sealed (tracer rounds, for example) after manufacture. But most of it just relies on the mechanical qualities of manufacturing to keep moisture out. This is actually pretty good, and serves fairly well in the case of metallic cartridges. You don’t have to worry about a brief exposure to water, from rain or dropping a round into a puddle or something. You should avoid allowing non-sealed rounds from sitting in water for a prolonged period, since such exposure could allow water to seep into the cartridge and compromise the gunpowder. It could also lead to case or primer corrosion, which could weaken the structural integrity or loading problems. So, if you want to store ammo for a long time, keep it in some kind of waterproof container. Double-bagging, using a vacuum sealer, and related strategies should all work fine.

Oh – did you notice that I specified “metallic cartridges” above? Yeah. That’s because plastic shotgun shells are not as water-tight. They’re still pretty good, given modern manufacturing tolerances, but you probably want to be a little more careful with them for long-term storage. Just sayin’.

One other thing to be aware of: freezing can cause some gunpowders to “crack” – to make smaller particles. While it may not seem to be a big deal, it can greatly increase the surface area of each small particle of the propellent. Which can cause it to burn faster. Which can cause over-pressure. Which can cause case rupture or even potentially the dreaded “ka-boom.”

So, there you have it, whether you’re wanting to have a rainy-day stash, just stockpile ammo when you find a good sale, or are wanting to be accurate for your next screenplay – take these things into consideration and you should be fine. Modern ammunition is generally of very high quality, and very reliable. A little planning ahead on your part should maintain that reliability for as long as you want.

Because it’s better to have a gun than a club.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

There’s isn’t a lot that I would add to this piece regarding old ammo. But since I wrote this we’ve tested something like an additional 20,000 rounds of new commercial ammo from the biggest manufacturers to boutique ammo from small shops. And I continue to be impressed with just how uniform the quality has been — it’s easily in the 99%+ range. It’s to the point where if commercial ammo fails to fire reliably, I would always first inspect the gun to see what the problems was, because it’s much more likely that the gun has some kind of problem than the ammo.

Which isn’t to say that all ammo will work reliably in all guns. I still advocate that for self-defense firearms in particular, you should always run at least a couple of boxes of a given type/brand of ammo through the gun before considering it sufficiently reliable enough to depend on to save your life. YMMV, of course.
