Question on zeroing a 1022

[EX-Gold Falcon]

I've just picked up a ruger 1022 18 inch barrel with a Tasco ProPoint sight. I was planning to go out this afternoon and zero in the sight, so my question is whether it makes any difference to zero it in at 25 or 50 meters. I do not have a lot of experience with the 1022, or rimfire for that matter, always tended to stick with centerfire, but the price was right for this Ruger.

Thanks
