Bob what about Barrel indexing thimbles on a PCP ???

I had no idea such a level of attention to detail went into building a competition rifle.  I knew it was high, but I wonder who figured this out about barrels and how he came to the conclusion.  I imagine a mad scientist with half a dozen guns connected to regulated tanks at a hundred meter range and comparing the groups lol

I tried to send you a PM but it said your inbox is full :-).
