The .22 caliber can refer to both centerfire and rimfire cartridges, but the most common .22 caliber ammunition, such as the .22 LR (Long Rifle), is rimfire. Rimfire cartridges have the primer located in the rim of the casing, while centerfire cartridges have the primer centrally located. Other .22 caliber options, like the .22 Hornet or .22-250, are examples of centerfire ammunition. Thus, it depends on the specific type of .22 cartridge being referenced.
same as today- .22 rimfire.
No. MOST of them are. The most popular "22" in the world is the .22 Long rifle cartridge, which IS a rimfire- as is the .22 Short, .22 Long, .22 Extra Long (obsolete), .22 WRF, and the .22 WMR. HOWEVER- there HAVE been .22 centerfire cartridges, such as the .220 Swift, 22-250, and a European cartridge, the .22 Velo Dog. .22 caliber means that the bullet is 22/100ths of an inch in diameter. None of the centerfire rounds will interchange with the .22 LR.
Assault rifle is a legal term, and laws vary place to place. Under MOST of them, it is a centerfire semi-auto rifle larger than 22 caliber, with a removeable magazine that holds more than 10 rounds, and a pistol grip. The SKS does not have a pistol grip, and has a fixed 10 round magazine. Not an assault rifle.
The 30-06 caliber is still in the #1 position as far as popularity by the shooting public.The 223 is running second,and the 243Win.caliber is a distant third.
Any caliber can do the job. Most states regulate what can be used.
Not necessarily. Centerfire and rimfire refer to the cartridge. Those with a primer in the center of the cartridge base are centerfire, and those with propellant packed in the rim are rimfire. Popular centerfire cartridges include the .223 Remington, .380 Winchester, .30-30, .30-06, 7.62x39, 7.62x54R, etc. The most commonly known rimfire cartridge is the .22 Long Rifle. There are bolt action rifles manufactured for each type of cartridge.
Both Shinsung and Sam Yang make a 50 caliber air rifle. The largest caliber Weinrauch makes is a .25 caliber.
Good rifle, good caliber for most uses. Did you have a specific question?
