Hi Earl and welcome.
Before buying a telescope sight, keep in mind that .22 specific scopes are usually set to be parallax free at 50 yards, while high power scopes are set to 100 yards.
If you plan to shoot to 200 yards with your .22 rifle, consider a good high power scope with lots of elevation adjustment. I personally use a 10X Unertl for our 200 yard rim fire matches, but I do see Leuopolds on other rifles.
A good scope for what you want to do will probably cost as much or more than your rifle.
Here are a few ballistic charts for the 22 RF through 100 yards for your consideration as well as my 100 and 200 yard rifle, a Pre A Model Winchester 52. I might add that for such an endeavor you'll want to buy the best possible ammo for your rifle. Buy standard velocity match ammo.
I might add that shooting a .22 RF at 100 yards in a prone match is much like shooting a 30 caliber rifle at 600 yards as far as windage adjustments go. Lots of fun.
Good luck and have fun.
