   Oh fuck, really? I just deleted such long post by accident...    
   Ehh, gonna make it shorter.   
   I never thought about lightsabers as plasma, but you make interesting point   
   here.    
   On MHD bullets, such gun still needs moving parts, bullet has to detonate in   
   chamber, to not damage other bullets.   
   Ok, so railguns don't throw gasses out of barrel, except for rail vapor, and   
   their bullets are accelerated with the same power through whole barrel, while   
   in normal guns you have gasses and acceleration gets smaller with pressure   
   going down. Would it    
   make a lot of diferrence?   
   On penetration, I completely forgot it's not only about speed and weight but   
   also about caliber and material. Depleted uranium in titanium would make a lot   
   of mess, probably making light armor vehicles obsolete. I think it's worth to   
   mention an    
   interesting system from pre WWII time, in my country (Poland) army designed   
   anti tank rifle that adressed a problem: when anti tank rifles penetrated   
   armor, they made a few schrapnels and you hoped for them to kill or injure the   
   crew, so it was hard to    
   destroy tank. So the engineers used works of one German scientist, and   
   designed a bullet, that was just a big chunk of lead. They made rifle that   
   shoot them with very high velocity, and it had an interesting effect on armor.   
   It squashed on steel plate    
   and made nice circular hole, giving so much energy to armor, that it melted,   
   and bullet with armor made a vapor inside the vehicle, that inflicted burns to   
   crew. What would you think about using it with this ChemRail thingy?    
   Okay, so tomorrow I will post something more about setting.
