agreed. I think we both know Jon and in that i doubt very much his POI is shifting? so i aint got a clue. I do know he does a mystic combination of dialing and hold over/under that would baffle Stephen Hawkins but it works for him.
Ive just gone with what is the safe option for me another Big Nikko, i haven't noticed any scope shift on the one i have at the moment.
When I was 5 I wanted to be like George Best
At 10 I wanted to be Nigel Mansell
At 40 I wanted to be like Tiger Woods
At 50 I want to be like Gilly
Just shows how life can kick you in the nads
