3rd generation = electronic ignition IMO.
Bigblock455,
CVA already tried that recently and the rifle was a "close-out". One of their few failures. Remington had the "electonix" varmit rifle years ago and that was also a flop.
We will certainly see the continued evolution of substitute powders.
I would like to see a breech loading Sharps style rifle that can be easily reloaded from a portable tree stand that uses a 209 primer.
