[QUOTE="aroshtr, post: 786341, member: 9176"] That picture is a great example why the [B]SCOPE[/B] has to be perfectly level. The conversation Mark and I were having has to do with the [B]GUN[/B] not being perfectly square under an (already leveled scope). Lets assume a 308 shooting a Berger 168gn vld at 2650fps. (just guessing) Actual bullet drop at 600 yards would be about 60" The 60" would represent the Radius of our imaginary circle. The circumference would be about 377", each degree would represent 1.047". The measure arc of a 10* cant would cause a miss of about 10". The picture Outlaw posted appears to be at about 5* cant per line not 10*. Which would put the groups about 5" left, and 5" right of the ceterline. I can't tell what size dot they were using so it makes it difficult to confirm how far from center the impacts were. I wanted to make sure the readers were not confused about the difference between a scope being level, vs having to get the bore in line with the scope. Joel [/QUOTE]
