Ammunition

There are 22 caliber centerfire cartridges such as the .22 Hornet and others, but ordinary 22 cartridges (short, long, long rifle) are rimfire.

16 gauge, 2 and 3/4 inch, any shot from fine birdshot to buckshot.

Unless your owner's manual for the PT1911 states that the barrel is rated for .45 ACP +P ammunition, I would not risk damaging my pistol, or myself trying to shoot this powerful load. Regular .45 ACP ammo is more than sufficient for most circumstances.

Yes, 38 caliber ammo is available.

Check with the local police . . . they often will take ammunition and dispose of it.

Yes. The more powder the bigger the bang and the faster the bullet moves. The faster the bullet goes, the more heat energy it will generate because of friction, and the initial blast from the powder.

Caliber is used to relate the diameter of a projectile (bullet). Its possible for two projectiles to have the same diameter, but vastly different weights/masses. One bullet might be 3 times as long as the other, although both have the same diameter. Caliber is typically measured as hundredths of an inch. So a 38 Caliber implies a projectile with a diameter of 38/100th of an inch, or .38 Cal. Notice the leading decimal point in most caliber designations. .45ACP is 45/100th of an inch. ACP is a special, patented shape of round designed by the Colt company for its automatic pistols. ACP = Automatic Colt Pistol.

Try different brands to see what works best in YOUR rifle. Federal makes very good ammo that shoots well for many people.

I have had good success with Federal rifle ammo.

Any automatic and most rifles

The armory.

They come in different sizes. 50, 100 and 500 are the most common.

The caliber is defined as the diameter of the projectile that a certain firearm fires.A good example is the 308 Winchester.This is a rifle that fires a .308in.diameter bullet thru the barrel of this firearm.Most firearms fire a projectile that is under a 1/2in.in diameter projectile.They range in size from .223 to .452"in.I hope that you find this informative.

It does not.

Usually all members of a firing squad are firing live rounds. However in some cases one member has only a blank cartridge.

No.

It depends on the hardness of the bullet's nose, the distance travelled, and the thickness of the metal sheet.

It depends on several factors, the main one being the propellant charge.
