Especially on neck-sized brass with a properly-cut chamber with +/- .-002" headspacing...

When do you chamber a round while hunting?

I believe it's because it takes a certain KE to cause the chemicals in the primer to react. If you slowly decock it, the KE is not large enough to pierce the primer and cause the chemical upset.

Is there a facepalm emoji?
Because you are letting it down slowly...

Wouldn't I still get an indent in my primers?

I'm not doing any Hollywood magic here... Try it yourself on any bolt gun, take it out and rotate the cocking piece until the sear lines up with the bottom of the cam in the bolts rear. Then tell me how far your firing pin isn't sticking out of the bolt face.

So then in order for it to hit the primer hard enough for a discharge wouldn't it have to be recocked and have the full force of the spring?

No, because the energy was not strong enough to damage the primer. You might see a rub mark. I think that's why everyone is against it, because hypothetically, if the firing pin is resting on the primer and there is a sudden jolt from dropping or whatever the case maybe, it can have enough KE move through the firing pin or the cartridge, depending on direction of the shock, to set it off. It's the same principle with using pointed bullets in tubular magazines and them being under recoil as the rifle fires. This is all me talking out my ***, I am an engineer, though!

Otherwise I would think even the decocking process would cause a round to be fired...when the pin drops (decocks) it goes pretty quick - it isn't this gradual slow thing...

I never decock on a loaded round, so I wouldn't know the actual speed of a firing pin being decocked. I also don't know the speed required to fully puncture a primer. It must be significant, though, because I'm sure we have all seen light primer strikes that clearly dent the primer but do not set it off.

depends entirely on how fast you lower the bolt handle.

Try this then. Put the rifle in condition C like you describe. Pull the trigger in and use a small tool to push on the cocking piece. If you're right, it will go further in to meet the primer.
But it won't.
