I am of the mind that you should hold it only as tight as necessary to secure it against the recoil. Squeezing can cause shaking.

So a .22 you would hold quite lightly. A .44 mag, quite tightly. If you use weaver stance exert isometric pressure by pushing forward with the spoon hand/arm and pulling back with the weak hand/arm. Not hard. Again- just enough to counteract the recoil level of the spoon. This technique really steadies out your sights. IMO weaver is vastly superior to isosceles for precision shooting.
