The snap caps are certainly a good idea.

With that said, if you are fighting a flinch, then having someone load the gun for you -- sometimes loaded sometimes not -- and observing your behavior is an excellent exercise and one we do all the time -- without snap caps. This is with bolt action centerfire rifles.

IMHO, the "gain" of dry firing by far out weighs the possible "downside". If doing an "away from home/remote hunt", then one should have a back up rifle in camp anyway. Given the never ending mantra of "shot placement" dry firing better be okay. It is a key element of observable simulation as a flinch is lost in the recoil of the rifle and cannot be observed, sensed by the shooter perhaps, but not readily observed.
