RAB,

I think on the asteroid, the bullet never returns, because escape v = sqrt(2GM/R). For the largest asteroid I can find, that means <1000 mph velocity. A decent rifle round will leave the tube traveling at 1500 to 2500 mph with earth gravity. So, bye bye, it's gone. The moon's escape velocity is ~ 5000 mph.

When it comes to black holes, I give up. Far more theory than fact is known about them.

BUT

I did think about the problem a lot more, and just to make you happy; posted a solution above under the name: IT CAN BE DONE. Hope you find my solution a bit intersting and amusing.

Steve
