no typo mate just the way my set up is i suppose ,changed from 30yrd wich was causing me problems with the way the pellet is on the rise ,having to aim at the bottom of a 15mm at 18+ yrds whilst allowing for wind was not easy (in strong wind) so the 25 zero i just had to think about my windage.
my set up is
jsb express 7.9
sport match mediums
chairgun tells the same story as the trials on paper ...
my pal shoots the same set up as me to the very same weight pellet and his is diffrent
so who knows..lol
