Whgil,st i take your poinbt, i was really trying to highlight the stupidity of some of the wording on my FAC, others have similar issues, it makes no senses at all.I think that depends entirely on your definition of zeroing. I have the same condition but interpret it differently to you.
I like to zero at different distances and from different positions to ensure I know my bullet drops to ensure a clean and humane kill. How many rounds does this 'zeroing' take? As many as needed until night am comfortable the rifle is zeroed. When I do this zeroing it may be on improvised targets or on a range but it's still zeroing and not just target shooting.
