I am looking for some advice on my Hawke Frontier scope 30 FFP 5-25X56. I have zeroed the gun at 30 yards and due to restrictions on my property have never had the opportunity to shoot past 50 yards. The other day I attempted to dial up past 5 mil on the elevation turret but was unable to. I have the return to zero stop engaged so essentially i cam only dial up from 0-5 mil . The scope is numbered up to 8 mil so effectively I have lost 3 mil of dial up ability. Can any one advise the reason behind this ....i have checked online and they say you have to re-set the optical zero. If any one has experienced the same and can offer advice on how to resolve this it would be greatly appreciated.
