[QUOTE="Mram10us, post: 1892106, member: 111667"] Here is a decent write up. I didn’t read it all though. [URL unfurl="true"]https://www.accurateshooter.com/optics/canting-effect-on-point-of-impact/[/URL] Bryan Litz confirms Tubb’s observation. Bryan tells us that, as a general rule of thumb (for common cartridges), [B]a 1° cant will produce five (5) inches of lateral displacement at 1000 yards[/B]. Thus, if you cant your rifle just 8°, the POI would move 40″ from the center of the target, putting the shot [I]off the edge[/I] of a 72″-wide target. [/QUOTE]
