Depends on target, distance and pocketbook.
From competitive shooting experience the longest distance is 200 yds with a .22 Long Rifle cartridge.
No. .22 Magnum and .22 Long Rifle are not interchangeable.
No

Yes
No. The WRF (Winchester Rim Fire) is a larger diameter cartridge. It is the same diameter are the 22 WMR (Winchester Magnum Rimfire) but is shorter than the magnum, It may be safety fired in a .22 magnum rifle, but not in a 22 LR. 22 LR ammo should NOT be fired in a rifle chambered for 22 WRF.
As in .22 WMR? That is the full name of the cartridge- the .22 Winchester Magnum Rimfire- usually called the .22 magnum
Remington has made many models in 22 magunm
No, My grand dad gave me one. as the kid I am, I tried this before . The .22 magnum is to big to fit in the gun.
$125-$200
With the exception of a few revolvers made with interchangeable cylinders, the .22 LR and .22 magnum cartridges should NOT be substituted for each other. The .22 magnum is a larger diameter cartridge than the .22 LR. Firing a LR cartridge in a magnum rifle will result in a split cartridge case, venting of gasses, etc. They cannot be traded with one another.
