May I use BB shells as training rounds for .357 revolver?

Here it is the BB shells for Dan Wesson air BB revolver. The size seems fit .357 mag Revolver. May I use them as training rounds? the prime/bottom has a hole and I guess it won't hurt the real firepin.

At the range? Of course you can...but why lol?

There is a airgun section on here btw, those appear to be meant for the listed models of airguns.

I meant dryfire/load/unload my .357 Magnum with those airgun BB rounds for practice.
