As it stands, the bullet does about 20x more damage than the charge does, the charge does about the same damage of a water bubble.
This might apply to the neutralizer as well, but I only own the Biohazard, so I have no idea.
In PVE the biohazard charge does about 2.5x more than the standard bullet, and it would be great if this lined up with the LD damage.
I once loaded 5 charges on someone so he could run into his teamates and boom for fun, but when it boomed he was still alive...
If it did the damage it was supposed to do, he would not have been living.
