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.
Length of the case. <><><> Despite the similar names, .22 Magnum also has a slightly larger diameter than a caliber 22. LR cartridge.
22 is a rimfire, 222 is a centerfire.
The 22 is slightly larger in caliber
The .22 bullet is smaller than the 9mm in size, (about 6mm) and is lighter in weight.
The Magnum case is actually just ever so slightly wider, longer, and holds relatively a lot more powder.
22LR high velocity - MV= 1260 fps 17 HMR MV= 2550 fps A lot faster, huh?
22 short, 22 long, 22 long rifle or 22 magnum depending on what it is chambered for.

The value of an Iver Johnson Magnum 22 caliber revolver would be dependent upon a number of factors. Some of these factors would be the age and condition.
It depends on what you mean. Strictly speaking, a .223 cartridge has a .22 caliber bullet, but when people say .22, they are usually referring to .22 Short, Long Rifle, or Magnum cartridge, which is different than .223.
