I don't see a scope level on any of your multitude of chikkens. How do you deal with 'cant' ?
Good grief....
Bryan Litz confirms Tubb’s observation. Bryan tells us that, as a general rule of thumb (for common cartridges), a 1° cant will produce five (5) inches of lateral displacement at 1000 yards. Thus, if you cant your rifle just 8°, the POI would move 40″ from the center of the target, putting the shot off the edge of a 72″-wide target.
Something to consider with those 2000 yard pokes.
Something else to consider.....If YOUR eye isn't good enuff to get within those "8 degrees", might I recommend a per-scription for new coke bottles?
