Wheeler Engineering Anti-Cant and Reticle Level System Review

Wheeler Anti Cant Review

This post was written by Dr. Jim and Mary Clary.

The primary topic of this article is to cover the Anti-Cant device; however, we have to insure that our scopes are “leveled” with our rifles before considering cant. There are several good systems on the market to level our scopes. We use the Wheeler Level-Level-Level because of the accuracy associated with bubble-levels that are used. The magnetic base level solidly mounts in the bolt track to level out the firearm. After placing the smaller level on the elevation turret we can properly align the scope. In case your scope has a rounded cap on the elevation turret, simply remove it and place the level directly on the turret’s top. Adjust the scope so that the bubbles in both levels are dead-center and lockdown the rings. The smaller scope level finds an additional use on our front rest at the firing range to insure that the rest is not canted.

The Level-Level-Level Kit has an MSRP of $24.99. Given the additional use of the small bubble level on our front rests during practice and competitions, it is a pretty good deal.

Wheeler Wheeler Engineering Anti-Cant

This brings us to the Wheeler Anti-Cant device. Benchrest, Palma and F-Class shooters are keenly aware of how canting can change the point of impact on the target. However, most hunters are unaware that even small cant angles can result in a missed shot. As such, few hunters have ever invested in an anti-cant device, let alone worry about the effect of canting on their hunts.

We hope that the following examples will convince you of the effect of canting and why you need to avoid it. You are at the range and have just finished sighting in your rifle. You pass it to a friend or relative for a few shots and low-and-behold, the point of impact on the target is not the same. One of you is canting the gun.

Cant errors become really noticeable when the rifle has been sighted in by a left-handed shooter and then passed to a right-handed shooter. How do I know? Well, I am left handed and routinely test new loads with my bride’s guns. When I hand the gun to her (and remember, she is a better shot than me), it never holds on the same point. Either I canted the rifle while sighting it in; Or, Mary canted the rifle when she was shooting. Using the Wheeler anti-cant device, we determined that I have been canting my guns for far too many years, and Mary, who used to shoot F-Class, holds level and steady. Thus, when she took her gun that “I had sighted in”, it was not.

If you regularly practice at the range with the Wheeler device installed you will get in the habit of holding the rifle level. The old saying “practice makes perfect” was never more true than when learning to keep from canting your rifle. With enough practice, you won’t have to worry when you take that shot at your once-in-a-lifetime trophy, you will be dead on. We kept the Wheeler anti-cant device permanently installed on our primary hunting rifles, just to check ourselves from time-to-time, as it folds out of the way when not in use.
Slight canting at close range in brush country is probably of no great consequence; but, if you are in the wide open spaces of the mountain west or on the open range, it becomes a major problem with long shots. We will never know how many animals have been missed or wounded due to canting; but, it is a problem which can be avoided with this device.

The Wheeler Anti-Cant device comes in four sizes, one for 30mm scope tubes, one for 1″ tubes, one for 34/35 mm tubes and one for Picatinny Rail attachment. With an MSRP of $39.99 it is a good investment.

    Capitalism will always win because we sell guns to all the other capitalists. Just saying as a prerequisite to all the “advertisement” whiners who hate your reviews because they don’t talk about the “negative side” of a product I mean really what the hell is he supposed to say. “The spring in the middle of the thing is ugly” I mean come-on guys get over it new variety in the market will never hurt the market just misinformed consumers over it

      Thanks, When we get complaints because we don’t have a negative comment it does tend to try a persons patience. I’ve always told these people we won’t make something up just to please those who think everything has to have a negative. Appreciate the comment.

      • Doc & Mary Clary

        Just for the record, Mary and I do not accept sponsors or advertisers. We started writing as a hobby which has grown rapidly in scope. We get scores of products from manufacturers each year…. those that we like, we write reviews on, those which we do not like (for any reason) we decline to write reviews and send them back with suggestions. There are lots of writers out there who have to sell their articles to make a living. As such, they have never met a product that they didn’t like. We aren’t that way, as we are both comfortably retired (military/medical professions) and this is our way of staying busy and providing information to fellow shooters/hunters. If a product has a minor flaw, we usually try to provide readers (and sometimes the manufacturer) with an after-market fix, or make a suggestion for improvement,. An example would be on our airgun reviews…. we have repeatedly expressed our wish that the company would use metal triggers instead of plastic. The plastic works satisfactorily, but metal would be much more durable… and that is in our articles. Thanks for reading our stuff and coming to TFB — a great site with great staff writers (we are guests).

    The angle of the reticle to the rifle is really irrelevant. In fact, most really-end shooters, such as Olympic shooters, set their rifles up at quite an angle to get a better fit to their body, and especially their shoulder pocket. The bullet leaving the barrel does not know which way the “top” of the rifle is.

    That said, the angle of the reticle to the ground is CRITICAL. This keeps windage adjustments from affecting elevation, and vice versa of course. It is critical to both have a ant-cant device, and make sure the anti-cant device is calibrated properly TO YOUR RETICLE. Most anti-cant devices have a machined surface on their top. Confirm that it is level with your scope turrets (which hopefully are level with your reticle on any decent scope), and you’re good to go. Leveling to the action on the rifle is little more than cosmetic.

      if you always shoot at the same distance, then the angle doesn’t matter. But, if you change distances, then the angle of the barrel – relative to the sighting line, does matter. If the rifle is zeroed at an angle, at X distance, then the bulleth path won’t simply be up/down relative to the zero at greater distance – but also slightly to the side. That is why the offset open/backup sights will be slightly off at a distance. But I mean, slightly off here means like an inch.

        @ Martin- You are effectively saying the same thing as Scott, however what Scott mentions first and last is that the reticle does not need to be aligned to the rifle, it needs to be aligned with the world. As long as the reticle is level to the world, your rifle can be at any angle you like. I personally need to angle my rifle or my butt plate to get into a comfortable shooting position for non-bench targets.

    I definitely second this article by Dr. Jim and Mary Clary. Based on my own experiences with two Weatherby Vanguard rifles ( one in .300 Weatherby Magnum and one in .308 Winchester ) as well as a Savage Axis in.243 Winchester, an FAL battle rifle in 7.62mm x 51 and a vz.58 assault rifle in 7.62mm x 39, the Wheeler Anti-Cant Levels are definitely most helpful in achieving longer-range accuracy by eliminating potential errors associated with canting. The stated MSRP’s are also pretty close to actual available on-line prices at most reputable dealers such as natchezss.com, midwayusa.com and cheaperthandirt.com. The only real factor that makes for an overall end price difference appears to be the shipping rates, so make comparison checks on these for your particular area before you buy.

    Ah, canted reticles. Those tick me off to no end, last time I was swapping the scope mount on my 10/22 (it’s an airsoft version, and it comes obnoxiously tacticoolized by default), I mounted the scope minimally canted (I haven’t noticed it until after putting the scope on the gun). Since I didn’t have that Wheeler thinger, I had to make do with two small levels instead, but it helped.
    Now, as for the Wheeler thinger, I see its usefulness, and let’s stick to that.
