I'm sure many have already tried this or seen the "You Tube" videos concerning the use of an endoscope for reloading purposes.

You can purchase an endoscope online from $12 to $35 dollars on up.  I would recommend buying a high definition (HD) camera!

It attaches to a smart phone/pad.

The software that came with my Non-HD camera didn't work with my Motorola pad so I had to find and download compatible software. :-[

Since I'm pack-rat by nature... I happened to find two different sized plastic sleeves that I glued together to act as the housing for the endoscope camera. 

I placed electrical tape around the smaller end so that it would fit in the center hole of my Dillon reloading head.

Attach the camera cable to your smart phone/pad.

Turn on your smart phone/pad and now you have another way to visually monitor the progress of your progressive press.

The camera also provides additional light.
