Keeping your scope perfectly aligned is critical to long-range accuracy and the Wheeler Anti-Cant Indicator is a pivotal tool for ensuring your rifles accuracy. Canting your scope, even just a couple of degrees, can cause error in point of impact. 
With modern "Drop-Compensating" scopes, an Anti-Cant Indicator is a necessity. If your gun isn't aligned correctly, dialing up the turrets, or using hold-over marks, will just throw your shot off. This error can easily be enough to cause misses. 
The Wheeler Anti-Cant Indicator ensures that your rifle is always held near perfectly vertical, eliminating any chance for "Cant Error" to cause a miss.
