It's early in the morning, so my mind is a little hazy, but with today's technology, we can use railguns to achieve speeds of Mach 7 or 8. The only problem with railguns is the heating. Titanium, or perhaps even Titanium Carbide would work to increase its heat tolerance. As for Coil Guns, I don't know too much about those, due to there not being very much information when I looked. I looked again and couldn't find much.
Gauss's law may be expressed as:
\Phi_E = \frac{Q}{\mathcal{E}_0}
where ΦE is the electric flux through a closed surface S enclosing any volume V, Q is the total charge enclosed within S, and ε0 is the electric constant. The electric flux ΦE is defined as a surface integral of the electric field:
\Phi_E = \oiint{\scriptstyle S}\mathbf{E} \cdot \mathrm{d}\mathbf{A}
where E is the electric field, dA is a vector representing an infinitesimal element of area,[note 1] and · represents the dot product of two vectors.
Since the flux is defined as an integral of the electric field, this expression of Gauss's law is called the integral form.

I'm good with math, but this is beyond me. It doesn't help that I just woke up either. All I can really say is that it would be reasonable to have some kind of railgun or gauss rifle by 2042. I think that a rifle of both kinds would be able to reach about Mach 4, but only due to power constraints. That being said, the weapon would probably need a mini-reactor.
Sorry I couldn't be of more help.
