I've noticed this as well on both very high velocity and relatively low velocity impacts.
I made a conventional cannon that will shoot a 1 ton osmium slug at 3.15 km/s. It has an energy of around 15-17 Gj. I've made conventional cannons pushing 30 Gj kinetic energy and they behave much the same. More often than not it bounces off of whatever is getting shot at regardless of armor composition and thickness. When it does penetrate it just vanishes with the module it hits.
I also made a railgun that shoots a 1g slug of graphene at 1.35 Mm/s. It's pushing 900Mj of energy. It seems to either zip right through armor with zero spalling, only do module damage,and disappear or bounce off harmlessly.
This was all done without nodding limits.txt as well, so it's for sure something on the game's end.

I have been running tests on this and while the game engine does seem slightly off it's not as far out as you might think. I used a modded fictional ultra high tensile strength, ultra dense material to see if I could convince a rail gun projectile to blow through both sides of my armour test bed and simply could not do it, even at very high masses and low velocity. The interesting thing about that is that my Whisker KKVs will do it quite happily. Not sure what's going on with that but I am happy to put it down to extreme cases giving rise to weird results.

I made a 600mm, 400kg round conventional gun with a muzzle velocity of 1.1 km/s. When fired from a ship moving at roughly 6 km/s, giving projectile energies of roughly 20 MJ, it seems to behave just as you'd expect it to, that is punching through a Gunship's armor on the first hit. Maybe there's some variable that's missing here? Because I don't see any unexpected behaviour on my specific case.
Edit: wait I mistyped that, I meant to say 20 GJ, not 20 MJ. It's not a pea gun after all.

I am confused by the output energy of the guns you guys say you have, my mass driver shoots much heavier rounds at much higher velocity, but its energy is not all that many times higher. Here is what happened when I put the weapon to the test against 50cm of VC steel:

Well projectile energy is just 1/2 * m * v², so there shouldn't be any room for discussion about that. It does imply that heavy guns fired from fast-moving platforms tend to be more efficient than sandblasters though, so you might want to keep that in mind. In case you want to see my results, here's the same 400kg-round cannon fired from a 11 km/s platform, with a target armored by 1 meter of VCS. It seems the target can take one hit and bounce it off, but the next one will go straight through the armor and destroy anything inside.
