Re: Scope Canting
6 degrees of cant is barely detectable but can cause left or right missed of 4-6' at 1k. 6 degrees is the 1 minute hand on a clock. Not much.
Right hand hits at long range with a level scope/receiver is caused by spin drift and the coriolis effect.
Long range shooting is a process that ends with a result. Once you start to focus on the result (where the shot goes, how big the group is, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
