Er........... No Simon, the amount of offset (within the bounds of reason of course) between each manufacturer is pretty well academic to the sniper, as is the distance between trenches and anything else. The only thing he's concerned with is distance. There is no earthly logic in the zeroing at 300 yards theory........ it is doomed to failure at any other distance, near or far. Better to zero in exactly as taught, by the book as detailed by DRP in thread 27 and be sure that you'd hit the man at any (?) distance, albeit 1.5" to the right.

After reading 'the book.....' in thread 27, I cannot imagine for the life of me, some budding sniper telling the sniping school staff that he's had a brainwave and he's got a theory that it'd be better to zero his rifle at... and.......... Nope, it wouldn't work. Like I said. Better to hit 1.5" off or slap bang on if you aim off a tad than miss totally for want of remembering some mathematical formula. To be honest, some of them couldn't even remember the range scale clicks up the scale, knowing that it would be one of the end of course exam questions!
