Yes, but the amount produced has been sacrified to free up assets for the particularly in-demand calibers.
Yes, in the T Bolt
Whether for pistol or rifle, .22 Winchester Magnum Rimfire ammo is loaded with bullets ranging from 30 to 50 grains. The standard seems to be 45 grains.
The .22 magnum is more powerful, longer and a larger diameter than the .22lr. The magnumcartridge does not use the "heel seated" bullet of the .22 LR, and USUALLY has jacketed bullets. The full name is .22 WMRF (Winchester magnum rim fire) and they do NOT interchange with .22 LR. There have been a few revolvers built with two different cylinders to permit switching between LR and Magnum.
In most cases, no. The .22 Extra Long is an obsolete cartridge that has not been manufactured in many years. The .22 Winchester Magnum Rimfire IS currently manufactured, but does not interchange with .22 LR. Despite the similar names, they are different diameters.
First, it is Harrington & Richardson. Second- it depends. What is marked on the gun? H&Rs were made in .22 Short, .22 long, .22 Long Rifle, .22 Special, .22 WRF and .22 Magnum.
Not made.
The .17 Hornady Magnum Rimfire (HMR) IS the name of the cartridge. It is a bottle necked rimfire cartridge- similiar to a a .22 Magnum necked down to .17 caliber bullet. Bullets used in this cartridge may be several different types, but are typically 20 grains or 17 grains in weight.
WMR stands for Winchester Magnum Rimfire- and is the proper name for the 22 Magnum. They are the same cartridge. The 22 WRF is the Winchester rimfire, and is a shorter, less powerful version of the 22 magnum.
No. .22 Magnum may only be fired in a gun Marked .22 Magnum or .22 WMRF. Different length and diameter- as well as power.
You may hurt more than the barrel. The .22 magnum is a larger diameter CASE and BULLET than the .22 LR (22 is a name, not a measurement). When a LR cartridge is fired in a Magnum chamber, there is a high chance the casing will split, possibly blowing bits of metal and hot gasses out of the chamber. There ARE revolvers made that will shoot both- but they use different cylinders. Do not try this- it is dangerous.
A .22 revolver takes CARTRIDGES. Which .22 cartridge will depend on what caliber the revolver was made for. A .22 LR can shoot Long Rifle or Short cartridges, and a .22 WMR uses .22 magnum cartridges. They do not interchange. There are a few .22 revolvers that have 2 cylinders, and can shoot either cartridge.
NO! The .22 mag case is larger in diameter than the .22 long rifle case thus the chamber of a .22 mag gun is too large for a .22 long rifle bullet. If the bullet does fire, the case will split with unpleasant and innaccurate results.
