Depend on the rifle weight and caliber imo, if the riffle is qu’ils light(22lr for exemple) you don’t want to hold it too firmly( not over doing it) cause it will make it hard to steady it! If you use a medium weight rifle(7lbs) in a caliber that doesn’t has too much recoil then you can put just enough “force” to have it snug into your shoulder…. If you have a medium weight rifle in a more sturdy caliber like 30-06 and up I think a bit more “force” is needed to control the rifle and the recoil( hope that make sense lol)! By force I mean pushing the but pad into your shoulder firmly and holding the “pistol” grip firmly but not over squeezing! As for the forehand, it is, in my case the one who pull the rifle to my shoulder, so I hold the forehand firmly but again not over doing it!!
