Vincent, get real. The "rail guns" have been reality for 20 years. They (1) don't weigh 10 pounds; (2) they do _not_ reach orbital ranges. At least not anything a man can carry. Newtonian physics _still_ works. As does simple materials engineering. To reach the space station requires a _terminal_ velocity of 26000 feet per second. The projectile melts within 500 feet of the muzzle. The recoil will be _murder_. And yes, there is recoil on a rail-gun. > >As you might understand there is 4 advantages of this gun.

You don't understand rifles. Muzzle velocity is _unlimited_. In theory. In practice, recoil is not unlimited as a human is behind the gun. And in practice, the projectile has to arrive at the final impact point intact. My .220 swift will, if pushed with hand-loads, vaporize the projectile before it reaches the impact point. I've seen the "purple mist" more than once as I experimented with new bullets and higher velocities. Forget a rifle at those velocities. > >Third it can destroy that Hyatt tank with 'meters thick' armour. Though i doubt >it is meters thick.

Why don't you do your research? You can find the _exact_ thickness of tank armor if you want. Today's anti-tank DU projectiles are designed to penetrate over 1 meter of steel. Why? because new tanks have the equivalent of 1.5 meters of steel armor plating. > >Fourth advantage is that after you come up with some new Hyatt tank-design >(already seen many in CCC) i can still reuse my gun and again destroy your tank >as i just increase the speed of my gun a bit.

I'm not going to turn this into an ammo design thread. But if you try to fire a WWII round at 10000fps velocity, it will last about 100 feet. > >>> >>> >>>BTW #1: during the coldwar, the US developed a tactical nuclear weapon that was >>>shoulder fired.
