Another gun question

Thanks guys.

For a bonus point ..

What is the phrase for '1 pull of the trigger = 1 bullet, but you don't need to manually reload for the next pull of the trigger to shoot the next bullet' then please if its not a 'sub-machine gun'?

Sorry if I'm being slow ..

Semi Automatic

Semi-automatic.
 
No, I used to be one and Alex is correct you cannot go off base with any firearm.

Unless you have written authorisation to transport said weapon between two defined points (in which case ammunition cannot be carried in the same vehicle) or you are on a legally authorised patrol route cleared by both local authorities and police. ;)
 
1) Does the phrase 'sub-machine gun' mean, by definition, '1 squeeze of the trigger = just 1 bullet' or something else?

Sub-machine guns are machine guns that work under water, hence "sub" (submerged). It works like any other machine gun i.e. 1 pull of the trigger sprays bullets until you let off.

The Special Boat Soldiers (SBS) use these kind of guns for underwater ops.

2) A '12-ball shotgun' what does the 12 refer to? Is it number of mm of the barrel? Someone at work says every cartridge has exactly 12 ballbearings in it -- which I find very hard to believe.

You almost got this one but it's not normal ball bearings, it is lead balls. The more balls you have in the cartridge the smaller they are, and vice versa. That's why you use a 410-ball shotgun to shoot small stuff like rabbits or mice because it has 410 tiny little lead balls. A 12-ball is more like what you would use to shoot a cow or something big because there is 12 big balls.

3) Is it legal for army officers to take home with them pistols with live ammo? So they have them off-duty?

Only in Northern Ireland because of the UHF/IRA terrorists etc.

4) What is a 'dumdum' bullet .. one which is designed to spiral in the body, or make a bigger exit hole, or something else?

It is special bullets that have a flat top on them so that when they hit a bone in someone's body they will bounce all around inside and not just go right through like a normal pointy bullet. Like if you shot someone in the arm it would bounce up their arm and in to their torso and basically blend up their insides until the dumdum bullet runs out of kinetic energy. They are banned by the Army because they are too lethal.

5) Hard one this. If I got a bullet and jabbed the firing pin with a house nail as I was holding it quite tight in my hands .. would it go off or just be pushed downwards by the nail?? (Sorry, wierd that last question)

I wouldn't recommend trying it but I think the firing pin would get pushed in to where the gun powder is and eventually the nail would just push the top bit out of the bullet, making it useless. It has to be pushed really fast to go off so the friction can ignite the gun powder inside the bullet. Faster than your hands would allow.

and authorised by the home office
 
Incidentally, sub-machine guns don't necessarily have to be fully-automatic. The weapons in use by armed police officers in the UK are, for the most part, semi-auto only.
 
Kwerk, please tell me that was a failed attempt at an amusing post?

1 - A sub machine gun is simply a small machine gun, as stated above. It has no marine significance!

2 - The bore of a shotgun refers to the barrel diameter. The oz weight of the cartirdge indicates the weight of the shot load in it. Shot is typically lead, steel, or bismuth.

4 - Hollowpoint. Designed to expand on impact to cause maximum soft tissue trauma. Very poor at penetrating any form of armour.

5 - Possible, but you would make a horrific mess of your hands. As you would fooling around with a shotgun cartridge as stated above, it would NOT just go "Fssss".
 
For No. 5

Bullets can be fired outside of the barrel, you need to be able to crimp the rim in the same way that the firing pin would have done against the chamber. Unlikely that you could do this by just holding the bullet, brass is too hard, you would need to hold it against a solid surface.

What you can do though, is pinch the rim in a pair of needle nose pliers (ones with wire cutters at the pivot work well) gently first to hold it steady, then squeeze hard and fast to crush the primer. I wouldn't recommend doing this with the lead part still attached as it will provide enough resistance for the brass (and lead itself) to fly off in random directions pretty fast. You can use the pliers to twist off the lead part first, then go ahead, it just makes a bang and a puff of smoke like a blank.

Source? I used to do this with misfired .22 rounds at the summer camp I worked at - misfired ammunition couldn't be thrown in the trash so I would take them apart. Usually (because it was cheap ammo) the firing pin had knocked the primer out of the rim instead of crushing it, in which case I'd just collect the powder grains for fun later on :D but sometimes the primer was still there too, just hadn't worked the first time, all sorts of experiments done on these :)

You can hold a flame under them too, this made a much louder bang than crimping the rim for some reason, I never figured out why...
 
We used to break up .22 rounds that miss-fired in cadets as well. I think we did try to set off the primer a couple of times, but failed.
