Future Weapons: Railguns

I get a little hot and winded reading American Handgunner, so to read about the US Navy's sweet foray into the world of railguns got me going this morning:

The Navy would like to have a fully functional 64-megajoule system aboard a ship by 2025.

A shot of that power could reach a target 100 nautical miles away in a matter of minutes. The projectile would travel so fast that no warhead is needed; kinetic energy is sufficient to destroy its target.

Killing baddies with the shear awesomeness of fast moving metal! RIGHTEOUS, RIGHTEOUS!!!!

Now, the Navy wants to have this weapon adorning their poop deck by 2025, which isn't all that far away. My hopes are to be toting one of these beasties with a walnut stock in the backwoods of the Old Dominion no later than 2050 or so. Think it's possible?

Once I vaporize a few hundred groghounds and a dozen elk with very fast metal, I envision writing an article on the matter about how 10 megajoules is not humane enough to drop an entire herd of whitetails with one round, so it's best to stick with .22 caliber railguns or higher and leave the pussy .17 caliber rounds for the plinkers.
