Because scopes for centerfire rifles are satisfactory for use on 17 HMR and 22 WMR rifles, the range of available models is enormous. They are produced with fixed powers of magnification that include 2.5X, 4X, and 6X on up to target models of 24X, 32X, or higher magnification. Because of the advances in optics, zoom lenses for cameras have become more common than those of fixed focal length. This trend is also observed in scope sights. If you look at a catalog from a scope manufacturer, you will see that there are many more models available with variable magnification than there are of fixed power. Scopes with variable power are available in several ranges of magnification, but the 2.5-7X, 3-9X, 3-12X, and 4-16X are the most common although other ranges are available. Eye relief of scopes intended for use on centerfire rifles is around 3 inches or more, but rimfire rifles produce almost no recoil so that is never a problem.
Scopes made specifically for use on rimfire rifles (especially those in 22 LR caliber) are sometimes more compact and lighter in weight than those intended for use on centerfire rifles. This is reasonable since most rimfire rifles are slimmer and lighter in weight than most centerfire models. Many manufacturers produce so-called rimfire scopes in a wide range of prices, and to some extent the old caveat “you get what you pay for” applies to scopes. Large suppliers of outdoor equipment such as Cabela’s and Scheels market scopes with their own brand labels. Two of the scopes in the Cabela’s Pine Ridge line are a very nice 3-9X rimfire model that has a catalog price of $79.99 and a 4X model that sells for $49.99. These are good quality scopes that are representative of the lower priced models that provide good value and reliable service. When mated to a rimfire rifle of modest cost, the combination gives the shooter a rifle capable of fine performance. I have used two of the Pine Ridge scopes from Cabela’s with complete satisfaction.
