When I see images of many PCPs with floating barrels, especially those where not a lot of the barrel seems to be located into the breech block, I think of this potential issue. I know there are so many advantages cited for the floating design, but I still think I would feel more reassured with a more solidly mounted barrel. Also, Al, at a glance, despite the knocking that BSA PCPs seem to receive these days, it looks to me like more of the barrel is located within the breech block as compared to some others. And the HW100 looks nice and solid to me....and you don't hear many complaints about accuracy with those.
