All a little upsetting, really, but we've been aware of it for years.

It is a shame that the mighty HW haven't resolved the issue with many of the hinged lever models.

It wouldn't put me off and I own five 35s, two 99s, an older 50, a 55T and three 30Ss (soon to be four).

I'm hopeless at doing links etc. but Google up "Springgunning R7 Tune". It's a US tuner's site and makes quite interesting reading for those unaware of "the issues". Also goes into piston issues as have been pointed out here before (CapitalBee?).

In my view, the little 30 is just that much of a little jewel with its superb firing manners, accuracy and forgiving nature and warrants any effort required.
