Shooting HP backward?

Bit of an odd question but I'm sure people have tried it. If you shoot a hollow point in reverse does it expand to fit bore, minimal expansion or shape stay intact? Maybe the universal pressure, perpendicular to all surfaces, keeps it intact. Curious if anyone knows

Only useful at close ranges, but devastating on things like mice.... They will expand nicely at only about 500 fps....
Above photo an RWS Hobby at 500 fps into a bar of soap.... At higher velocities they can come apart....

That's cool. Was wondering about hollowpoint slugs in big bores not pellets. I see my question was vague.
Basically I keep toying with the idea of a double ended slug. I know a nose tail side is not needed and would have same effect as a boattail. But keep thinking about it for some reason so figured I'd ask what would happen to the hollow point end if that was valve side in the bore. Would the hp expand in the barrel from the pressure resulting in a skirt or does it stay intact as the pressure is reacting on all surfaces equally? You probably see where my mind was going with that, a dual purpose slug, one with say 60% meplat HP end and 70-75% sold meplat end. Silly? Sure but keep thinking about it anyway so figured I'd ask about it's expansion in barrel to either get it out of my head for good or go ahead and make a mold. LOL

I've heard of people shooting hollow base wadcutters backwards.
But maybe a hollow base wadcutters shooting forward is more close to what you are describing.
