RCBS makes the only one I've heard of. It has a probe that senses when a pistol case is short the minimum powder charge (which you set yourself). I. E., if I measure 5.4 grains of WW 231 for a 45ACP case, and set the lockout die for that charge, if the powder measure fails to drop at least 5.4 grains, the lockout die will sense the light load and stop the press from cycling a full stroke. That's the indicator that something has to be checked.
In my experience, it is not adjustable to measure rifle loads. The probe won't back out high enough.
