While playing on a server that had socom with LAW bullets, I noticed that I was able to kill others with one missile (damage was over 100000), yet I couldn't kill myself. Same happened to others. Suicides worked fine though with other weapons such as a m79 shooting a cluster grenade.
Edit#2: this bug only works online

Actually, it was the splash damage didn't work, not just suicides.

I'm not sure, I'll have to check that. LAW has a very little blast radius.
Edit: Right. Splash damage with modified weapons doesn't work at all.

Yup.. I ntoiced this too , while using a barret modded to fire m79 shells.. I could only kill if I hit them as though I was still firing a barret bullet..

Strange.
