Just had a thought regarding this issue.
I would assume that the mag indexing pin is operated by some of the released air pressure in the system when taking a shot. If so, it may be that the pin shoots up much harder on the FAC/HP versions we're all using and as such the mag lever hits the probe much harder than on the 12fpe versions in the UK, affecting accuracy more?
This may explain how as to Tony puts it, 'the majority' of daystate owners aren't having mag issues as I'm sure there are many many sub12fpe owners to dilute the pool.
It also may explain why I'm getting better mag accuracy on low power - on mine that's about 24fpe. I initially assumed it was the harder alloy of the H&n ftt I was using but I've since seen this trend extends to jsb 13gr pellets too. Halve the power output and I'm sure you see even more improvement.
