Thanks all (Except Ozzy!)
I managed to get a batch swap done at Otmoors so back up at the zeroing range and my groups are back to the way they should be, literally within 3 pellets fired!
I cannot believe a change in batch can make such a dramatic difference!
48 yard 5 shot group at 9mm centre to centre with hardly any outliers over the evenings shooting.
I think when I get time (Basically when I retire) I will do a decent test with this rifle to see what it can do.
As a follow up is clamping the action a good or catastrophically bad idea?

Slowly working my way through every conceivable way to miss tin chickens!
