CCI NR 9x18mm Makarov question

2 general questions:
a. I assume it is NR because aluminium is brittle. Is all alloy ammo NR?
b. TMJ (total metal jacket) is much less common than FMJ. Would not in this age of lead-phobia one may expect the exact opposite (i.e. ammo manufacturers be eager to seal and hide all lead)?

I’ve heard of cheapskates that have insisted on trying to reload the CCI Blazer cases. It isn’t very convenient as they use Berdan primers instead of the US standard Boxer. I certainly wouldn’t recommend it.

The CCI-Speer TMJ bullet is plated in the same fashion as their Gold Dot HP and SP series. I suspect that in the forthcoming political climate that there will be moves against lead core projectiles.
