What do you think will happen when you accelerate a projectile to Mach 7 in the length of the barrel..?
Well, if you know the mass of the projectile, you would be able to calculate the reaction forces and design the gun and it's supports to withstand these forces.
Is there something else you're trying to point out with your comment?
My point is, at the moment i don't think there are any materials that can withstand the forces involved, repeatedly.
"Accelerating a 1 gram projectile up to a mere 1% of light speed would produce enough force to send 100kg in the opposite direction at 3000 meters per second (9800 feet per second or 6000 miles per hour)."
Granted we're talking around 0.01%? The speed of light but the projectiles we're talking about here are likely to weigh significantly more than 1 gram.
