I know some of you folk use Z6 scopes with the ballistic turret which I am told can be used to zero a bullet for 3 distances...ie from say 100 yard ,150, to 300 for example so you dont have to change zero all the time ..except by clicking the preset turret. Might seem a daft question but could you use the same turret to zero for two different bullets?? Ie say I use pro hunters for Roe and a zero of inch high at 100 yards with for the first setting. Can I on the next setting on the turret zero it for another bullet of say 130 grain for say 150 yards? I realise the second turret marking wouldnt be good for the first bullet in the case.
