Rimfire ammunition differs from centerfire ammunition in that the firing pin does not contact a primer placed in the center of the cartridge. A rimfire cartridge has a flat, closed back with no opening for a primer. With a rimfire cartridge the rim of the shell is hollow and filled with the primer material. When the hammer engages the back of the cartridge it impacts the the rim, crushes it and ignites the gunpowder inside. This action causes the expulsion of the projectile. Because of the nature of the hollow rim, this type of ammunition has typically very low pressure rounds, which result in lower velocity and penetration.

When was the first bullet made?
The first bullet was made at 1883. It was a Smith and Wesson .22 caliber rimfire cartridge.
What are rimfire cartridges made out of?
Rimfire cartridges are comprised of a soft lead bullet, a case most often made of brass, and the smokeless propellant (powder).
How far can a 22 caliber rimfire loong rifle bullet travel?
Not quite 2 miles.
What parts are in a rimfire cartridge?
A rimfire cartridge typically consists of three main parts: the case, the primer, and the projectile (bullet). The case is usually made of brass or another metal and contains the primer and gunpowder. The primer is located in the rim of the cartridge and ignites when struck by the firing pin, igniting the gunpowder and propelling the bullet forward. Rimfire cartridges are distinct from centerfire cartridges, which have the primer located in the center of the cartridge base.

What is the lowest caliber bullet?
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.
How do you make a primer for a rimfire bullet?
A rimfire CARTRIDGE uses a dab of wet priming compound that is placed in the cartridge case, and the case is spun at high speed to force the material out into the folded rim. The priming material, usually based on lead azide, is an extremely sensitive explosive, and cannot be safely shaped or handled except when wet. After the material dries, the case is loaded with powder and a bullet. When the cartridge is fired, the folded rim is pinched by the firing pin, causing the primer material to explode, igniting the powder. There is no safe way to effectively renew a rimfire primer.
What does rimfire and centerfire mean?
A centrefire cartridge has a primer centred at the rear of the casing. This primer contains a charge which is ignited when the primer is struck (normally by a firing pin, though some guns will have the pin integral with the hammer), and this ignites the gunpowder whidh propels the bullet forward. Rimfire guns work in pretty much the same fashion, except that they don't use primers. Rather, the priming charge is packed into the rim of the cartridge.
What will happen if you unscrew the top of a 22 bullet?
The top of the CARTRIDGE is the bullet- and they are not threaded, so they don't unscrew. The cartridge case is crimped onto the lead bullet. Playing with ammo- especially rimfire ammo like the .22, is dangerous. If the rim (which contains the primer) is crushed, the cartridge can explode. Strong likelihood that is going to hurt you.
How much gunpowder does an average bullet have?
The amount of gunpowder in an average bullet varies depending on the type and caliber of the cartridge. Typically, a standard centerfire bullet contains about 3 to 5 grains of smokeless powder, which translates to roughly 0.2 to 0.3 grams. Rimfire cartridges may have slightly less. Overall, the specific amount can differ based on the bullet's design and intended use.
Can you legally hunt deer in Georgia with a 22 cal rimfire rifle?
No. Georgia law requires rifles or handguns used for deer to be 22 cal CENTERFIRE or larger, with an expanding bullet. While .220 Swift, or 22-250 is legal (with the right bullets) a 22 Long Rifle (rimfire) is NOT legal.
