I'm fairly sure I had some big shift problems with my HW77/CS1000 caused by recoil induced flex of the long M7 main fixing screw that was used with no lug. It was unsupported over a fair amount of its length and the legacy of this flex could be seen in the backward smear of some mounting pads I experimented with between the stock and the action. Only on the shot movement of the action within the stock could cause this smear.

Strange thing is that I used the gun for years with little or no problem. After trying to 'improve' the inletting (smoothing it out) the problem emerged. I think the old imperfections may have previously prevented the action moving in the stock....
hmm , think I know where your coming from , when I sit my action in the stock I have about 4mm between the wood trigger recess face and the forward mounting post face ( big screw post ), makes me wonder whether to almost washer this area up just in case the deeper inletting is actually splaying out a bit when you tighten it or causing a bit of movement, next thing I,m gonna check whether the action is sitting on the recess for the end radius of the trigger unit rather than the cradle it probably should be sitting on
