Your last sentence in the previous post was in reference to armor piercing. Barrel wear is a significant issue in the railgun research I've heard about (though not read), I guess it's just one more thing that's ignored for simplicity here? Or maybe lack of actual published knowledge... Though as I stated earlier, the 3x bore diameter barrel thing is a little puzzling. You actually can get an error from 'excessive melt ablation' depending on the materials used for barrel and armature in a railgun. Wear happens less when you're not in Earth's nitriding and oxidising atmosphere, but CDE probably is quite optimistic about it. Coilguns used to benefit greatly from wide bores as well, before they were fixed to conserve energy. Conventional guns were not also revised at this time, so perhaps something actually is wrong with them and they were never fixed.

Ah, cool! I'd hoped there was some actual knowledge about barrel wear, but it seemed just as likely there was nothing helpful.

I would love wear to be taken into account, though. Of course it could shift the meta even further towards laserstars, but OTOH I would expect things like modelling mechanical considerations, better reactor modelling, multi-intercepts and not allowing exit from tactical phase as long as projectiles are flying to hit laserstars particularly hard and even things out a bit.

Making something very stable usually releases a lot of energy, and in this case this something very stable is also a gas in relatively large quantities.

Oh come on - nitrogen is practically a poor man's noble gas. :P If the energy of firing a railgun can ionise nitrogen inside the barrel (as in the fiery US Navy tests), this could then bond with the rails and may even be forced into them by the travelling armature. Nitrided metals become very hard and brittle at their surfaces. Could be that the rails simply ablate away quicker than this becomes an issue though.
