barrett M82
NO!!! DO NOT ATTEMPT THIS!!!
A firearm meant to be fired from the shoulder, as opposed to a handgun.
Yes
It is a form of rifled cannon. In military terms, guns are shotguns, machine guns, and cannon. A rifle is a shoulder fired weapon. The minigun is not.
DO NOT DO THIS!!!!!!!!!!!!!!!!!!!!
If NOT fired from the hand or shoulder, AND has a barrel 20mm or larger in diameter, it's a cannon. The M203 Grenade laucher is 40mm, but fired from the shoulder- not a cannon. The Bradley has a 25mm Chain Gun- over 19mm, not fired from shoulder- cannon.
Caliber is the term used for the diameter of the inside of the barrel (in shotguns, it is called gauge instead). The larger the opening of the barrel (known as the bore) the higher the caliber- but not necessarily the energy of the cartridge. The .600 Nitro Express was a VERY large cartridge used for VERY big game hunting- elephants. But it is an older, straight sided cartridge. The .50 BMG, while firing a skinnier bullet, has more energy. The largest rifle made for sporting use was probably the .700 Nitro Express, however, military anti-tank rifles (fired from the shoulder) have been as large as 20 mm- about .80 caliber. Some muzzle loading black powder weapons fired a 1 inch, or 1.00 caliber bullet. The king of the BIG bore is probably the Paradox- these were part rifle, part shotgun- that were measured in gauge rather than caliber. The largest, the 2 bore, fired a slug about 40 mm in diameter- or 1.600 caliber.
No. An RPG (Rocket Propelled Grenade) is a shoulder fired weapon.
a bullet of the same caliber and same grains of powder fired from a long barrel will have a higher muzzle velocity than if fired from a short barrel.
No. They will be too large to fit in the gun or be fired out of the barrel.
Depends on the angle it's fired at, and which .30 caliber. When fired at an angle of about 45 degrees, a 30-06 can fire a bullet about 4-5 miles.
