PhysCallbackDamage() queues up the damage event so it occurs after

Calling UTIL_Remove() or delete on an entity during a callback may

Unless you want the entity to have a physics hull or something, then
you'll need to increase the max allowable speed. You can do that by
modifying:
ConVar
There are three issues here:
1) Collision representation for the bullet
In HL2, they are point sized. You can also make them out of
boxes or fully general vcollides.
2) Velocity of the bullet
In HL2 the velocity is infinite - they travel instantaneously
until they hit something
The vgui vertex has two members, and screenspace position (in screen
coords) and a texture coordinate (in normalized UV space). You can get
the screen dimensions from the vgui surface with
surface()-GetScreenSize().

It sounds like your prop is set to a collision group that doesn't
collide with the player or you've got the player set as the prop's
owner.
