Nah not really Jim, I'm a lifelong engineer and can appreciate technical and chemical ingenuity. Such as Forsyths experiments with fulminates to create the flash, through roll primers and the tipping flask to fill the flash pan. Things moved at a fast pace and just about stopped with the first cartridges. There has been refinements but little real innovation.

Some stuff just defies logic, like how the hell did they come up with the crazy idea of pin-fire. It's kinda like inventing a wheel with flats on so it dont roll away.
