As an addendum to my posts with photos of "new age" bedding blocks, I suspect the reason some (not all) bedding blocks for conventional bolt actions like the Remington 700 and Winchester 70 is the blocks have LOTS of contact with the action. And of course actions vary in dimensions slightly.
The trend I have seen with newer actions is far smaller bedding blocks, which thus have less contact with the action--which means epoxy-bedding will also have less effect. And as somebody already mentioned, the actions themselves are often far stiffer.
Offhand I can't remember how many newer rifles use this type of smaller "bedding block" (which may not even look like what many define as a bedding block), but would guess the total would be at least 10, both American and European. Have yet to be disappointed in the accuracy of any.
Of course, this often also involves better factory barrels, often hammer-forged.
