Remington tried all of that with the "Etronix". It used special primers in it's ammunition that fired electronically. Lock time was reduced to all but nothing. It was a total flop. Voere, tried caseless ammunition in a bolt action rifle. It also was a flop. Gun people are traditionalists. Look at how long it took the Glock, along with synthetic stocks to really gain acceptance. Electronics and guns just don't seem to mix. A bit like putting mag wheels and a spoiler on a stagecoach. Bill T.
Bill, you are missing some facts, Colt's first revolver Company went broke, The "Patterson" while a technological innovation was a commercial flop. Glock did not invent the Polymer pistol, it's Steyr predecessor was a commercial flop.Those are just 2 examples off the top of my head.
The problem with caseless ammo (Walther has been working on it for decades ) seems to be residue fouling. the rest of the technology was pretty much perfected by Daisy back in the 60's. (I forget the designation, M25 will know, he's got one )
The electronics industry has advanced greatly since the "Etronix" which predates cell phone technology, let alone something like the Droid.
Another thing we may be overlooking is air guns. They are available now in rifles that will take most game. It woul not take much to convert that technology into a practical, reliable larger bore SD hand gun.
Another possibility is "Guided" ammunition.
