USB camera for powder check

wrote: The thing that scares me the most in my reloading endeavors is a squib. To visually check every case for the proper amount of powder is inconvenient and slow. (but better than two in the tube or a hand grenade) I load /shoot about 1k/month. So, I'm going to mount a small camera that will display a real-time video that is easy to see from my position operating the press. I have a five station progressive press and there are a few powder-check dies available that work very well, but I don't have a station to spare between the powder dump and the bullet seating. I use a separate crimp die after the bullet seating. (I did start to design an eight station press but how obsessive CAN I get?) Get just ONE squib and you'll never shoot the same, it'll always be in the back of your mind. Thankfully, I've never had a double-charge! I can mount the camera on the ram so it's focus it constant or I can mount it to the press if the camera will auto focus fast enough to be useful. Ideally, the camera would have it's own LED lighting source. Any recommendations on a camera or refinement of my idea? Imagine if the camera took a still at the bottom of the stroke and instantly compared the image to a "standard" then sounded an alarm if the image was too far from the standard and locked the press? Again, a powder-check die would do just that but I would not be able to use my bullet feeder or my separate crimp die. I think Ive got a short..very short focus video camera. It originally was on a microscope. If I can find it Ill check it out and send it to you. Btw..all those air cylinders were sold at auction. I hadnt marked each one individually with my name..so the **** wouldnt let me have the ****ing Crate of brand new air cylinders back.
