If you carry a revolver you can't use FMJ which means you are restricted to lead.
FMJ generally refers to a bullet that is fully encased on the front and perimeter but with an exposed lead base, while FMC generally refers to a bullet that is fully encased on all sides.
In lieu of other documentation clarifying item #3, I presume that conventional JHP bullets with a copper-jacketed base and open tip are acceptable, as they are neither FMJ, FMC, "armor piercing" nor "exploding." (+1 Tom.) If the writers of the manual were savvy enough to use the terms FMJ and FMC, I would assume that they were also knowledgeable enough to more clearly and explicitly prohibit JHP bullets if that was their intent.
FWIW I suspect that the allowance for FMJ in semi-auto firearms is a holdover from the bad old days when many auto pistols would choke on anything other than FMJ hardball.

...why no wadcutters? Are they more dangerous than a lead round nose or flat point?
Likely another holdover due to a widespread old-school perception that wadcutters are only good for punching paper. FWIW early 1970s gel tests demonstrating that 148gr hollow-base wadcutters are MORE effective than the conventional and near-universal 158gr .38Spl LRN bullet were initially met with some head-shaking disbelief and incredulity, so this may reflect some ax-grinding by conservative writers decades ago.

...what is a .45 163 ACP pistol.
Most likely a typo.
FWIW some older word processing software would write hidden formatting characters into the text, which may pop up as random numbers or nonsense characters if you open the file in newer software that's not fully backwards-compatible. Back when floppy disks held only 512K and hard drives were exotica that only university research labs had, word processors couldn't write lots of auxiliary formatting code into files or you might run out of disk space.
