Haha...kind of funny, a few years ago I thought about a rifle with this design. Looks like someone beat me to it
You need a special rifle with special ammo (conventional primers won't work).
I thought my idea would never catch on because the cartridge as we know it would have to change, and then there is the problem of providing the electrical current. Would a battery be used, or something more like a grill starter?
See, the 9v battery was the weak point. They should have had a way to charge a capacitor manually within the rifle, that way you will never have to search for batteries AND bullets.
For this type of firing mechanism, should a primer really be required? I think it would be possible to design a permanent "spark plug" type primer that never had to be removed. Just pick up the casing after firing, clean it out, load powder, bullet, and fire.
I still think the design has potential, but batteries can't be there, and primers should be permanently installed.
I have thought some on this subject and it seems to me an eclectric trigger could be used with the traditional firing pin assembly. That way present ammo and primers could be used. There would be no creep and unlimited breaking lbs.(or oz.) Looks to me it would be the best of both worlds. Any Ideas?
That's what I mean. A good electric system would eliminate all firing pin and primer failures.
It would also allow bolt action rifles to be operated with ease, since you wouldn't be drawing a spring back while ejecting a spent cartridge.
As mentioned above, the trigger in these firearms could be nearly perfect, since all it would do is send a signal to release an electrical charge.
The only problem is making the cartridge have a permanent primer, and creating a way to store a charge (Some sort of pump mechanism might work well, allowing the user to build up an electrical charge my moving a coil over a magnet, or something of that nature).
