RE: Scope for 22 WMR.
You have to forget regular 22 scopes for a .22 Magnum - because a .22 Magnum is more like a high power rifle than it is a regular .22 Rifle.
I have a 4 x 12 x 40 Simmons on one of my .22 Magnums and I have a Tasco 3 x 9 x 40 on the other.
Both are capiable of shooting one inch bulls eye's at 300 yards with the right ammunition.
A regular .22 is sighted in for 50 yards. A magnum can and will shoot 300 yards!
Using a .22 Magnum to shoot 50 yards would be like hunting rabbits with a 300 Winchester Magnum. Too much over kill.
Both would get the job done - but the .22magnum can and will do more than a regular .22!
