Canted Reticles — Serious Problem Needs to Be Addressed

Unfortunately, we still see too many scopes sold to the public with canted reticles. The problem of canted reticles is a serious issue that some manufacturers (both domestic and foreign) have failed to address. (Note: here we are talking about an INTERNAL scope assembly problem that results in reticles being off-axis relative to the turrets. Don’t confuse this with the canting which occurs if you don’t level your rifle. A canted reticle is a scope production defect requiring factory repair.)

One degree of scope reticle cant is noticeable. Three degrees is “slap in the face” obvious and, frankly, pretty unpleasant to work with. Unfortunately, three degrees happens to be one major domestic scope-maker’s production tolerance. And sure enough, you can find this company’s scopes in retail outlets with the reticles located a full three degrees off-axis.

We believe that badly canted reticles are unacceptable in a high-dollar scope, one costing more than $450.00. Optics-makers — it’s high time to improve your quality control.

Three degrees may not sound like much–after all it is less than 1% of a 360-degree circle. Nonetheless, as the diagrams show, three degrees of cant is VERY noticeable in a scope. In fact, most people will be bothered by a reticle that is just one degree off-axis. Canted reticles are not just annoying to look at, but off-axis reticles cause a number of problems with sighting and accuracy. For example, if you set up your rifle so the vertical cross-hair is straight up and down, your turrets will be slightly tilted. This means that when you click elevation you will change windage slightly, and vice-versa. If, on the other hand, you cant (or tilt) the whole rifle to make the turrets square, this throws off the bullet trajectory–causing bullet impact that is low and displaced horizontally*.

Now, all manufacturers can have a production flaw now and then. Yet we’ve never heard a complaint about canted reticles in Nightforce, U.S. Optics, or Schmidt & Bender scopes. So, it IS possible for the better manufacturers to get it right. Our point here is that it is time for the major scope-makers to address this problem and improve their quality control. That will happen sooner if consumers pay greater attention to reticle alignment during the purchasing process. If you have a scope with a canted reticle, send it back to the maker and ask for the problem to be fixed. If enough shooters do that, we expect the scope-makers will take notice and improve their products.

JROTC Air Rifle Competition Underway at Camp Perry

From February 12th through the 28th, Camp Perry hosts more than 500 high school Junior Reserve Officers’ Training Corps (JROTC) cadets from across the US and Department of Defense Schools overseas. The cadets will be competing in the All Service Air Rifle Championships to determine Army, Marine, Navy and Air Force JROTC national individual and team champions. In addition, the top competitors in each championship will advance to the National JROTC Air Rifle Championship at Fort Benning, Georgia in March.

Camp Perry’s new Marksmanship Center facilities are comparable to the best airgun ranges in the world (such as those in Beijing and Munich) that host International Sport Shooting Federation (ISSF) competitions. Gary Anderson, CMP’s Director of Civilian Marksmanship, said, “our state-of-the-art air rifle range [is] the finest facility of this type in the entire Western Hemisphere.”

CMP Air Rifle match

The JROTC competition process started last November when nearly 7,000 cadets and 1,200 JROTC unit teams began firing on CMP-provided postal targets at their home ranges. The CMP then used its Orion Visual Imaging Scoring system to scan and score the 21,800 10-bullseye paper targets electronically.

Competitors in the JROTC Championships will fire with either “precision” or “sporter” class air rifles. In general, precision rifles are high tech and feature adjustable stocks and triggers, internal rechargeable air tanks or CO2 cylinders, etc. Sporter rifles are low-cost, conventional appearing air rifles without specialized adjustments, but they also utilize air or CO2 cylinders to power their projectiles. The competition entails 60-shot three-position events to be fired on two successive days. Each day, competitors will fire 20 shots each in prone, standing and kneeling positions at bullseye targets placed at 10 meters.
