Yes, there is a name for it, and yes, it is possible
_shell = "BulletSingle" camcreate getpos Pos
This will create a slooooow moving bullet at that position. To give it speed use the setvelocity command
_shell setvelocity [0,1000,0]
Other bullet choices are:
BulletSingleE: I have no idea what the difference is between this one and the top
MachineGun7_6: I'm not sure if this one works
MachineGun7_6Manual: Ditto here
MachineGun12_7: Yeah, ditto here too.
I've only experimented with BulletSingle and BulletSingleE. I'm getting the machine gun bullets from the offline Comref
