More links on ram accelerator, which I think could be just the ticket for launching sulphur. It's much better than a gun but performs similarly in that it fires a shell. It benefits from cheap propellant, low pressures, low acceleration, no barrel friction, etc. leading to the ability to launch big fat payloads in a cheap, low-tolerance gun at low costs. With a long gun, like a mineshaft, it should be able to launch big fat projectiles right up. Alternatively, you could put it in a large plane to get shells up the last few miles that a big heavy plane can't get up. The benefit of using a big shell is that aerodynamic drag is lower and the 7 km/s muzzle velocity should be easily enough to get the necessary lift.
Anyone got any objections?
