Your reference to having a box fitted in your chest reminds of reading once about a 96 year old English woman, one of the landed gentry, who got her pacemaker fitted on the opposite side of her chest to that where it is normally fitted so she could carry on with her passion for shotgunning gamebirds. She had been advised that once fitted with a pacemaker (presume from this it is on the right side of the chest?), recoil from a gun would not be ideal so hence her instruction to the surgeon. I would think the recoil from a 9.5lb TCR in 450-400 would be getting up on the brisk side. My Mauser 404 in that same weight lets you know it means business when firing off the full power 400gr loads.
