The general rule that is mostly true a lot of the time is that "caliber" is the diameter of the bore (the hole inside the barrel through which the bullet passes) as expressed in decimals, using inch units of measure. So a "thirty caliber" rifle would have a bore of .30 inch or 30/100 inch. A "twenty two caliber" gun fires a .22" diameter bullet.
But "caliber" also means a particular name of a specific cartridge of a certain height, weight, width, angle, and gunpowder charge. For example, a .22 "long rifle" bullet weighs 40 grains and moves at an initial velocity of 1000 feet per second. But a .220 Swift rifle cartridge fires a bullet of the same diameter, but longer and heavier, and at over 3,000 feet per second. Two different caliber cartridges, but in each case the hole in the rifle's barrel is about 22/100 inch.
I was not the question.
ECS stands for Environmental Control System in relation to the aerospace industry.
The original answer (below) is nonsensical as the question doesn't ask about MPH but rather MHP which, unlike miles per hour, bears some relation to HP, or horsepower. MHP means metric horsepower, which is 98.6% of mechanical horsepower. Mph stands for miles per hour and Hp stands for horse power, mph is a measure of distance over time and Hp is for the power that something posesses
It stands for bitmap (image file).
PNG stands for Papua New Guinea
The L in HTML stands for Language.
"Caliber" refers to the size of the bullet the gun fires, or more specifically, the size of the bore, which is the size of the hole in the barrel.
DO NOT DO THIS!!!!!!!!!!!!!!!!!!!!
If you're talking about firearms, caliber refers to the diameter of the bullet or the bore size of of the gun.
yes they did
there are dozens of calibers from .17 to .70
Need to know who made it, barrel length, barrel profile, caliber, type of sights, finish. Where did you get your definition of what "good" means in relation to firearms?
In relation to? Without more clarification, I can only assume that you're talking airsoft. GBB for airsoft stands for Gas BlowBack. I have never seen this term used in relation to firearms. That doesn't mean that it is not. I would assume that the definition would be the same.
50-260 or so
Any that have the appropriate sized barrel
In the usual sense of caliber, it means the diameter of the bullet. The smallest commercial caliber is the .17 rimfire, but there have been MUCH smaller caliber firearms, down to the 1-2 mm range. That is about .05 to .10 caliber.
Two different meanings for firearms. For artillery, caliber is the relation of the diameter of the bore to the length of the barrel. A gun on a Navy Destroyer might be known as a 5 inch 38 caliber- meaning it fires a 5 inch diameter shell, and the barrel is 38 times 5 inches long. However, for rifles and handguns, it means the fractions of one inch that equal the diameter of the bore. So a .30 caliber rifle has a bore than measures ABOUT .30 inches, a .50 caliber ABOUT .50 inches, and so on. Some firearms have measurements from the metric system- a 9millimeter pistol has a bore diameter of ABOUT 9mm.
Anywhere from $5 to $5,000. There are thousands of diferent .22 caliber firearms. Giv eus some information, and we can give you an answer.
