Book 1, Personal Combat, GunMaker examples, p. 227.
Mechanical/Textual:
Almost all examples given are wrong:
XRSMg-4 Experimental Recoilless Sub Machinegun -4 R=0 Cr32,400 5.7 kg Bullet -5
Machinegun = Bullet 4
Sub = Bullet -1
Experimental = no effect
Recoilless = +1
--snip--
ShPj-9 Shock Projector -9 R=2 Cr600 0.5 kg Pain -2 Elec -2
Same here. Projector starts at *-1. Am I reading T03 wrong? Does *-1 mean 'disregard and apply the damage from T04 and T05"?

All the things you listed appear to be wrong to me, too.
Not only that, but the range is also wrong on the XRSMg-4. It should either be R=1 or R=3 but I can't tell because the table has the "Recoilless" range modifier listed as -+1. I think it should be -1. So the base machinegun range of R=5 becomes R=3 when it is modified to a Sub-machinegun, Experimental reduces it to R=2 and Recoilless should decrease it to R=1; not R=0 as in the listing. Even if Recoilless should be +1 the range would be R=3.
As far as the *-1 question you raised, I don't think you are reading it wrong and I seem to remember in some of the 5.0 or 5.09 errata discussions it was determined that you are correct, but I don't remember for sure. Otherwise, it would be pointless to have any entries for Artillery at all as they would all be replaced by the Descriptor entry and there isn't a (blank) Descriptor for Artillery.
