of red or green lighting at five levels of brightness. Of course, if you choose not to light the reticle, you have a dual thickness crosshair that has a series of three dots on all sides of the intersec- tion. These dots are intended to make holdover or allowance for the wind a more exact process. Officially known as the Model
CPA416AORG2, the information in- dicated by that string of characters is CenterPoint, Adventure, 4-16x, adjust- able objective, and red or green indi- cating the choice of reticle colors. The scope measures 14.5 inches in length and weighs 18.8 ounces. It is a heavy but sturdy scope that focuses from five yards to infinity by rotating the objec- tive. This range is the result of the scope also being intended for use on airguns. Eye relief is listed as 3.1 inches, and like many other scopes, the eyepiece is of the “fast focus” type. At 100 yards, the field of view varies 22.5 to 6.3 feet, de- pending on magnification. To me, this model seems to offer more quality and features than others in the Adventure Class or comparable scopes from other suppliers. This scope is packaged with a sturdy (but too high for my taste) set of rings, flip up lens caps, and a CR2032 battery to power the light source. Like virtually all other scopes, the
CenterPoint is listed as “waterproof, shockproof, and fogproof.” Lenses are coated to provide sharper images and to reduce glare. Adjustments are advertised to be one-quarter inch per click at 100 yards. Although the 4-16x CenterPoint
is interesting for several reasons, the fact that the suggested retail price is just under $100 makes it even more in- teresting. However, this new model is already available in the large “mart” for a few cents under $70. So, I simply had to test one and Laura Evans at Crosman Corporation made that easy. The Adventure Class scopes
are intended for use on virtually all firearms and airguns. I have tested so many scopes on airguns that I have lost count so I decided to do something different. Consequently, I removed the 6-20x scope that my old 222 Remington 700 normally wears and mounted the CenterPoint. That way, I could test the scope at 100 yards rather than some short distance that is appropriate for airguns. However, I did not use the high
mount that came with the scope but rather a Weaver Quad Lock® of medium height. To see what the scope would al- low me to do with the 222 Remington, I prepared a batch of a favorite handload which routinely gives groups in the 0.60-0.75 inch range. That load consists of the 50-grain Sierra Blitz propelled by 20.5 grains of Alliant Reloder 10X. In Winchester cases with Winchester small rifle primers, that load has given very consistent results in my rifle. With the rifle supported on a rest,
I bore sighted the rifle on a target at 100 yards as well as I could. I then fired one shot at a target at 25 yards and made some adjustment to the scope. From that point, the bullets struck the target at 100 yards. My first test was to simply fire
a five-shot group. On the range near Buffalo, Wyoming, wind is a persistent problem and that was true at the time of testing. Waiting for favorable condi- tions between shots, that first group measured 0.87 inch. My next experiment was to assess
the accuracy and reproducibility of the click adjustments. One of the ordinary
ways of doing this is by the procedure known as “shooting a square.” In this procedure, a series of shots is fired to obtain a group and the scope is adjusted a certain number of clicks. My practice is to make the first adjustment upward, the second adjustment to the right, the third adjustment downward, and the fourth adjustment to the left. This should bring the point of impact back to coincide with the original group. More- over, knowing the number of clicks in each adjustment, it is easy to see if the
