I still think you’re not understanding. I’m not talking about the gun accidentally going off when the bolt is moved. I’m talking about when the bolt is not fully seated in the downward position and you fire the gun, the gun will misfire and will not detonate the primer.
To test it, my suggestion (the same thing that I did at least) is to take an empty case and put primer in it, and then start lifting that bolt a tiny bit and pull the trigger, then lift a little more and pull the trigger. Do this until the primers don’t go off. You’ll be surprised how little you have to lift that bowl to make the primers not detonate. I found it to be a bolt lift of about 1/4” and the primers would not detonate.
It didn’t take hardly anything to move that bolt upwards 1/4”. Thick gloves would likely do it.
