Thread: Anti cant consistency

your line of sight through the reticle is always at an angle to the bore (vertically, looking perpendicular to the bore) that's how you can zero your rifle. A 20moa base just gives you a little more angle to use for longer range shots. Zeroed at 100m the angle of line of sight through reticle to point of impact at 100m is the same with 20moa base or 0moa base.

if your scope is mounted to be tracking vertically with the rifle held on a cant you get a tiny angular displacement (unless you're holding it at 90° for some reason in which case the angular displacement would be your scope height over bore - i.e. 1.5 inches at 0, zeroed at 100 meters, 1.5 inches at 200 meters, and so on angularly increasing). But because no-one is stupid enough to hold their rifle at 90°, the angular displacement is just an insignificant fraction of an inch. The line of sight you are using remains the same whatever the base, the canted base just allows you to angle your line of sight further than the non-canted base
