The Bullet and the Shell












By Mark W. Danielson

I recently read a mass-market paperback by a name-brand author who has eight other books out. It was an easy read until a glaring error shot out my eye. Though blinded, I couldn’t block this slip from my mind. I was tortured, like fingernails dragging across a blackboard. This blunder was so large that a baseball field tarp couldn’t cover it; so blatant, it sidetracked me from the story. A bungle important enough, I had to post a blog on it.

So, what is it that has my feathers ruffled? It’s a scene where the protagonist is staring down a shotgun barrel, the cold steel aimed at his head with no chance of escape. The author has made several references to this shotgun; then someone moves, the gun fires, and the bullet hits. Yes, I said bullet! How can a publisher allow such a mistake? If you’re going to write about guns, then know the difference between a shotgun and a rifle; a bullet and a shell.

Tactical shotguns are used for close-in combat because you don’t have to be terribly accurate to hit your target. Sport shotguns are ideal for bird hunting because they send up a swath of BBs called “shot” that increases the odds of hitting something. Shotgun barrels are smooth on the inside, and have large diameters to feed shells full of round shot. A wad keeps the shot in place until it exits the barrel where the barrel’s “choke” or shape, spreads the shot at a predetermined rate. The farther from the barrel, the more dispersed the shot. For deer hunting, a “slug” replaces the bird shot. Deer slugs and bird shot both have limited range.

Rifles are normally used for long distance; pistols for close-in shots. Both weapons use bullets and have barrel “rifling” on the inside, which makes a bullet spin. The moment a rifle or pistol is fired, its bullet bursts from its casing and starts spinning. This spinning maintains the bullet’s trajectory until it either hits its mark, or gravity and the atmosphere end its flight. Whether it’s a sixteen inch battleship gun or a .22 pistol, the principle is the same.

Ben Small has provided excellent information on guns in his blog posts, and I’ve previously written about the importance of getting the details right. Whenever glaring errors like this occur, the author loses instant credibility. To avoid situations like this, take the time to research areas you are not completely familiar with. Even if only one percent of the readers catch an error, that’s one percent too many.

Poof!

by Ben Small

What if your protag or perp, in a hurry, picks up some ammo, plugs it into a gun and it goes poof?

Can this happen?

You betcha. I had it happen to me at the range a few weeks ago. There was a cloud of smoke and burning powder, some of which burned my cheek, and then the gun locked up. Yes, the bullet made it out of the barrel and there appeared to be no damage done, but I would not have been able to fire a second shot without clearing the cartridge and risking damage to the gun.

Not all guns and cartridges play well together.

So what went wrong?

Well, it could have been a hand-loaded cartridge, perhaps using the wrong powder or too much of it. Or it could have been a reloaded cartridge, and maybe the case failed. Bullets may look simple, but they are anything but. The standard cartridge is the product of precise development engineering and testing, where various corrosive or non-corrosive primers must be matched with cases matched to specific cylinders, each with dimensions proven through years of experimentation in controlled environments. But that’s just part of a bullet’s development. There’s also choice of powders, some fast burning, some slower. And on top of that, you add a bullet, which requires weight, composition and construction choices. Each manufacturer’s bullet is different, and there are many standard production bullet manufacturers.

And then there are the wildcatters and reloaders, those who make their own bullets. Believe it or not, there are millions of these people, and the market for bullets, cases, primers, powders and loading equipment is enormous. Take a look at Gun Digest, the leading gun magazine, considered by many as the place to look for gun ads. You will find pages of advertising for each of these items.

But that’s just the bullet side of it. You gotta consider the gun, too. Guns can be finicky about the ammo they’ll eat.

What prompted this article was my experience at the range. I was firing a high end pistol, a Sig Sauer X-5 9mm pistol, perhaps the most accurate production pistol currently made. It’s a match grade pistol, which means the fittings are tight. And I was firing Winchester Ranger ammo, again, a high grade of ammo.

Poof.

Now, it could have been a bullet manufacturing error, but if so, I would have expected to have the problem recur. And it did. But only in this gun. My much cheaper Beretta and Glock had no trouble with this box of ammo at all or with Winchester Ranger ammo in general.

A defective gun? Believe it or not, this match grade pistol ate the much cheaper aluminum cased Blazer ammo with nary a hiccup. And it ate all the other non-Winchester Ranger I fed it.

No, the answer in this case – pardon the pun ― was in the mating of the gun and ammo. Ask any gun expert about what ammo works best in any particular gun, and he’ll tell you he can’t know without experimentation. Usually this answer means accuracy will vary depending upon the individual characteristics of the gun, the barrel, its condition, the weather, lubrication, the weight of the bullet and how all these conditions work together.

But sometimes they don’t work at all. And sometimes the mating of ammo to gun can be dangerous. Guns do explode; people can be hurt. Usually, the problem is careless handloading, maybe a defective case, an improperly seated bullet or poor choice of powder…or too much of it. Or maybe the gun was poorly maintained, over lubricated or under lubricated. Maybe there was a bulge in the barrel. The Gun Zone - Springfield M1A
The Gun Zone - Glock



This stuff does happen. Kabooms aren’t common, but they occur. Jams are much more common, especially with semi-automatic firearms. That’s why some people prefer revolvers.

A gun owner who shoots his gun frequently will know what ammo it likes. But someone who picks up a gun or ammo may not have a clue. And some guns are more finicky about ammo than others. For instance, Glocks and Berettas feed on just about any form of standard production ammo. Springfield XDs and XDms seem to like heavier weight bullets. A Sig Sauer .22 LR Mosquito is notorious for having ammo preferences. Shoot modern .30-06 ammo in an M-1 Garand, and you may get a nasty surprise. The military version of .30-06 ammo, the bullets for which this gun was designed, use a slower burning, lower pressure powder.

What to do when the gun jams… A seasoned shooter will know; an amateur probably will not.

Clinging To Our Guns

by Ben Small



In anticipation of an Obama swearing-in ceremony, America has been buying guns in unprecedented numbers. Of course, Obama-phobia isn’t fully the explanation. Americans feel threatened; they’re afraid. Gang and drug warfare are on the rise, as are home invasions, and in some cities, like Chicago, which is setting murder records, only the cops and bad guys have guns. (Ordinary people aren’t supposed to defend themselves in Chicago. Mayor Daley won’t permit it.)

But there’s no denying the Obama effect. Overnight, prices of AK-47s skyrocketed, in some places as high as 200%. Same with AR-15s and other weapons carrying more than ten rounds. You may remember the Clinton Assault Weapons Ban. That didn’t do much to stop the proliferation of serious weaponry. It was a joke. Yes, magazines were limited to ten rounds. But there were no limits on how many magazines one could carry.

Several articles have appeared about surging guns and ammo sales across the nation, and the gun stores I’ve visited have been packed full of purchasers eager to beat expected new anti-gun measures. Barack Obama has said he supports gun control, and his legislative record backs him up. Yes, there was the Supreme Court’s Heller decision, but that victory for Second Amendment gun rights was by a one vote margin. Change a judge, and it’s a new ballgame.

But something else, too is driving the buys. A different fear.

Mexican drug gangs are storming our border, shooting up border towns and killing police officers and border guards from El Paso to Tucson to San Diego, and of course, their Mexican counterpart cities. And the Latino gangs that support these drug lords, like MS-13, are spreading across our lands like an infection. MS-13 is in Los Angeles, San Diego, Tucson, El Paso, Chicago, Madison, Minneapolis, Phoenix, and other cities as well.

Just last Halloween in Tucson, my home turf, three teenagers in three wrong places at three wrong times were shot down, two of them killed. All three were students at Sunnyside High School. Three normal kids with bright futures, students of a friend of mine. One of these kids, a young girl, was at a party. Some gang-bangers tried to crash, and an argument ensued. Later the bangers came back. They shot up the house from their car. The girl, inside dancing with friends, died.

My teacher friend says the kids know the ropes. You’re sitting at a stop light and a car pulls up. Someone in the other car flashes a gang sign. You’re not in a gang or you’re in a different gang; you don’t respond or you give the wrong sign.

That's disrespect.

Bang, bang, you’re dead.

Amazing. Imagine being a teenager today...

A few weeks ago, my wife and two of her friends took their Concealed Carry Class and submitted their permit paper-work. The class was jammed. The instructors said classes have been packed for more than a year; they're struggling to keep up with demand.

Now these are ordinary citizens. Not gang-bangers, not criminals. You can’t get a concealed carry permit if you’re a criminal. Nor can a criminal buy a gun – legally. But criminals don’t have any problem getting guns, all kinds of guns, even automatic weapons. They just smuggle them in from Mexico and spread them around the gangs. The guns that are terrorizing Chicago aren’t guns held by law-abiding citizens; they’re gang guns. No gun ban is going to stop that trade. Only law abiding citizens are denied the means to protect themselves in Chicago.

Our growing security anxiety is fueled by several very real concerns: 1) fear that our institutions are breaking down; 2) fear that wealth re-distribution policies will heighten tensions; 3) fear that anti-gun measures will limit purchases by law-abiding citizens of weapons and ammunition; 4) fear that like the L. A. riots after the Rodney King beating and the looters and marauders during and after Katrina, there will be roving gangs of looters and predators following any future catastrophe or breakdown of food delivery, power supply, energy or social order; 5) fear that terrorist or gang or drug lord raids within our borders will increase; 6) fear that our borders are so porous, we have no ability to stop drugs or the growing illegal gun trade, and 6) fear that the police cannot adequately protect us.

A Harvard study a year or so ago examined the effectiveness of strict gun control measures worldwide. The study concluded that those jurisdictions that have the more severe gun limits, have higher crime rates. Look at Chicago or Washington, D.C. Indeed, Britain, which completely banned most guns many years ago, has seen violent crime rise since.

Already, some silly measures have become law, and are being considered elsewhere. Like the California law that requires every handgun sold by 2010 to imprint on its cartridge identifying marks traceable to the gun. This law was passed last year by the California legislature and signed by the Governator despite no proof that such technology exists or would be effective. In fact, a study by the University of California at Davis, showed that such technology does not work. And what about revolvers? Their cartridges are carried away with the gun.

Imagine how easily you could be framed. Go to the gun range, fire your weapon. Someone picks up your brass and leaves it at a crime scene.

Boom. You’re in jail.

The gun industry has reacted slowly to the California measure, although at least one manufacturer has decided not to sell guns to police or anyone else in California if this law remains in effect. A few other manufacturers are considering similar actions.

So called “assault” weapons are defined very loosely. The term is usually described as semi-automatic weapons, those that don’t have a rotating cylinder feeding a bullet to the chamber. Banners claim these weapons aren’t used for hunting; they're only used to kill people.

That's not true. On either front.

Varmint hunting is popular these days. Rats, prairie dogs, coyotes, they're fair game in many areas. And semi-automatic weapons, both pistols and rifles, are popular choices for hunting them.

I've owned semi-automatic weapons for over ten years, and I don't hunt.

I haven’t killed anybody.

I shoot paper, lots of paper. I compete in paper-shooting contests. Fun stuff, shooting in competitions, part of our American heritage. Sergeant York, an American hero, used to compete in turkey shoots. So do I, but my turkeys are paper, and they’re taped over cardboard.

And what’s wrong with that? Good clean sport. Nothing gets killed, and only a few pieces of paper and cardboard are damaged. The paper, bullets and cartridges are all recycled.

Shooting is green.

So who gets hurt by me owning a gun... or several?

Semi-automatic weapons fire one bullet at a time, just like revolvers do. Yes, magazines for these guns may contain more bullets, but some revolvers shoot as many as eight rounds, and there are speed loaders available. Speed loaders facilitate a revolver rate of fire not far slower than a semi-auto's.

Pick up any gun magazine; there are many from which to choose. Check out the ads. Yes, they may scare you. But remember, these are the guns the good guys, law-abiding citizens, are buying. They're used for self defense and for sport. A gun ban won't stop gangs from getting guns. Criminals don't file for concealed carry permits, and they don't buy their guns in U.S. gun stores. You bump into a bad guy at the wrong time and place, and the only thing between you and the coroner may be your ability to defend yourself.

The bad guys may have machine guns. And sometimes, grenades.

Back in Connecticut, a Revolutionary War cemetery adjoined my back yard. Stones dressed with flags mark the war's graves. In those veterans' days, every home contained a gun.

We may return to that notion.
