44, I mostly agree. My earlier post was made in a fit of rhetorical grumpiness.
I agree that outright ammo bans—or administrative near-bans—are seriously unlikely to pass Constitutional muster. Furthermore, IMHO the mere idea that gun bans are off-limits but ammo bans are A-OK is an obviously puerile sham, and I suspect that most gun-control advocates beyond the Politico-commentator level are intelligent enough to realize this even if they don't say it openly.
I am concerned, however, with the creeping incrementalism we see with certain types of ammo (i.e. the Sporting Purposes test, and attempts to classify ammo as AP when it clearly fails to meet the legal definition). Our main focus should be to make sure that additional types of ammo do not fall under similar legal umbrellas.
