Ammunition

The A-10 Thunderbolt carries 1,174 rounds of linked 30x173mm ammunition for its primary weapon, the GAU-8/A Avenger rotary cannon.

17 grains - ballistic tiped or 20grain in hollow point

About 3,400 yards.

The extractor, which is part of the bolt. It clamps around the shell casing and has a ridge which locks into the cannelure of the shell casing (small indentation near the base of the cartridge which goes completely around the casing).

They can be- in areas where a lot of people fire guns in the air for celebrations. Depending on the size of the bullet, it can fall with enough speed to cause injuries or death.

The longer the barrel the more time the powder has to fully burn inside the barrel, which in turn increases the pressure inside the barrel and the muzzle velocity of the bullet. This generally results in greater recoil. (though not necessarily greater "kick") Though other factors must be considered as well.

For many small caliber rounds like the .17 and .22 you're not going to see any noticeable increase in recoil going from a 18" to 22" barrel.

Another much greater factor is the ammunition. Cheaper ammunition, such as typical store brought ammunition, has a less powerful powder or simply less powder all together than brands or custom loads. Lets take a .308 for example. A .308 cheap bullet isn't going to have any noticeable difference going from a 20" barrel to a 24" barrel. However, change the ammunition to (just for a good example) Double Tap Ammunition, and now there is more likely to be a noticeable difference from even a 22" to 24" barrel.

Next up is the grain of the bullet itself. A heavier grain is going to generally have more recoil. (the heavier the bullet.. the harder it is to move.. the more energy from the expansion of gasses is transferred back into your shoulder.)

Another important factor is the action of the gun. Bolt, sing-shot, break-over, pump, etc. have greater recoil than auto / semi-auto (gas or mechanical). since none of the energy is being absorbed to chamber the next round. (Also with gas operated barrels the size of the gas port can also change the recoil of the weapon, though typically not enough to be noticeable)

Now lets get back into the question. Does a short barrel or long barrel kick harder. The energy being transferred back into your shoulder is generally greater the longer the barrel, but often feels less 'instant' and more as a shove.

EXCEPTION! - In general, a longer bull barrel will have less recoil than a shorter standard hunting barrel, since the bull barrel weighs more. (heavier the gun the more energy required to move the gun the less recoil)

Grain is the weight of the bullet. They are measured in grains as opposed to grams or ounces. I'm sorry I can't tell you where that started.

Powder is also measured in grains.

because the TNT they worked with was harmful and the toxic powders involved in making it turned their skin yellow, over 400 'canaries'died from overexposure to TNT.

When gunpowder detonates, it creates a gaseous byproduct which expands very rapidly. The expansion of this gas is what propels the cartridge through the barrel.

That depends on the game laws where you live. In the US, each state has their own fish and game laws, and they vary from state to state. Check the game laws in your state.

Most any rifle employed in the Second World War by any warring faction would have been capable of killing multiple persons, provided they were lined up correctly. The standard German service rifle of the time period was the Mauser Karabiner 98, which fired a 7.92x57 cartridge, and could very easily go through multiple persons. Medium machine guns of the German military used the same cartridge, but these rounds were fired in rapid succession.

Anti-partisan forces, death squads, and the like typically preferred rapid firing submachineguns for this task, however, such as the MP 38/40, or the Finnish Suomi M1931.

For the most part, the steel cased ammunition marketed by Wolf, Brown/Silver/Golden Bear, etc. Keep in mind that Wolf isn't actually the manufacturer, but rather, a marketing companies who obtains the ammo they sell from a number of sources, and not everything they market will be priced so low. Wolf Gold, for instance, is brass cased ammunition made by Prvi Partisan in Serbia, and is considerably more expensive than the steel cased Wolf ammo (such as the Military Classic), which is manufactured at the Tula Cartridge Works in Russia.

I believe the standard was 40 rounds but usually ammunition was in short supply and a lower number of rounds were issued.

Caliber refers to the diameter of the bullet the gun fires. The caliber of a 9mm is 9 millimeters. That is about .356 inches.

Marlin has made dozens of different model .22 LR semi-auto rifles. The "lubricated" indicates an early rifle- that is now taken for granted. You best route will be to have an experienced gunsmith examine your rifle, or sit down with a copy of Gun Traders Guide or the Blue Book of Gun Values, and look through the Marlin rifles until you find yours.

The term is cartridge- that is a cartridge case, powder, primer, and bullet (that's the part that comes out of the barrel) It is extremely dangerous to attempt to remove a live primer from a loaded cartridge. Once the primer has been fired, reloaders use a tool called a deprimer to push the old primer out from the inside- but pushing on a LIVE primer will almost certainly make it fire. Very unsafe, please do not fool with that.

The .40 is a larger diameter round. The projectile has a dimension of .4005, versus the 9mm Parabellum, which has a dimension of .356. Of the two, the .40 is the more powerful cartridge.

Single shot, bolt action, pump, semi-auto,

Anywhere from 400 to 1200 rounds per minute. Some Gatling guns can fire 6000 a minute, although they may not be considered TRUE machine guns.

Most are in .380 ACP caliber. Sometimes called 9mm Short in Europe (or 9mm Corto or 9mm Kurz) What is marked on yours?

One cartridge is about 20 cents retail. When the military buys in huge quantities, it is less.

Yes, these models exist, mainly due to the fact that the Czech Republic joined NATO in 1999, they had to use the 9mm rounds because it was standard issue to pistols used by NATO members. There are other varieties for commercial use, for example, the pistols offered by CZ-USA.
