Well, it has a bit of compliance when cured. I've redone a couple of weight tubes (not mine) where the epoxy had fractured and the tube was loose because the front of the tube was never bedded to a solid recoil seat. A lot of it depends what's inside the butt.....rigid foam, expanding type foam, just air, etc.
On actions where the back wall of the tang is used as the recoil lug, there's a lot of energy transferred through the pistol grip area....'way more than most would realize.
Good shootin'
