Gerard,

I hate to say this, but BS.

If that was the case, I would think that out of 20 or so DR's that I have used / own, just by the numbers / percentages, one of them would have developed OSR.

Now add all the DR's used in the BGRC Comp, the same would apply and a hell of a lot of shots get fired through DR's here in Aust.

Sorry, don't agree with you.
