lead metal and sodium nitrate
Once upon a time I read in a publication that a 'very powerful' mix could be make by mixing finely divided lead metal + Sodium Nitrate.
I presume it needed a detonator.
Is that correct.

Probably not. Plus, you don't want to poison the air and everything with lead, I suppose. Don't work with heavy metals.
Rest In Pieces!

Molten lead can be used to reduce sodium nitrate to nitrite. Some members have produced nitrites in this way (search for the thread)

Lead cant be powerful reducer, or give high vods and I haven't heard of the idea of mixing lead azide with oxidizers, I'd more likely mix it with
boron. I've heard lead is pyrophoric, can there be uses for powdered lead like exotic fuses or something?

I'm just not getting why so many people recently want to be putting huge quantities of lead/Pb compounds and vapor into the air.
They outlawed leaded automobile gasoline for a reason, and the tetra-ethyl lead in petrol was a tiny fraction. Now we are talking about grams, tens
of grams, kilograms of Pb going up in smoke, to be inhaled and to land on (and contaminate) surfaces, the environment, hands, etc.
There are so many other interesting energetics that don't come with the dangers of large amounts of lead.

Tin is a good replacement for lead in many chemical applications. It shares most of lead's properties, and is significantly less toxic.

While it might be a satisfactory replacement in some reactions, there are also quite a few significant differences:
Tin dissolves in hydrochloric acid, whereas lead is not attacked. Lead dissolves in nitric acid, whereas tin is only dissolved with great difficulty
(due to protective coating of meta-stannic acid that forms on surface hindering further reaction). Stannous salts are reducing agents, and under
alkaline conditions can reduce Bi+3 salts to bismuth metal. An alcoholic solution of Tin(II) chloride can spontaneously ignite after prolonged
exposure to air. Solutions of stannous nitrate are unstable, and such solutions can be hazardous in concentrated form. Plumbic oxide, PbO2, is an
oxidizer, it reacts with hydrochloric acid to release chlorine.

I'm not saying let's go kill all the stupid people...I'm just saying lets remove all the warning labels and let the problem sort itself out.

It appears that lead is still used in aviation fuel.
lead makes for paranoia . If you 'made your own' leaded fuel by adding 2.5 grams of the lead compound to pure gasoline most people watching you make
it would then refuse to handle the (leaded) fuel or go near an aeroplane that was burning the stuff.
You should of course avoid lead as much as possible. If lead is a bad as people make out ALL YOUR PARENTS (if not yourselves, depending on how old you
are) ARE semi-brain-dead zombies.
wiki
TEL remains an ingredient of 100 octane avgas for piston-engine aircraft. The United States Environmental Protection Agency and others are working on
an economically feasible replacement for leaded avgas. The current formulation of 100LL (low lead) aviation gasoline contains 2.12 grams of TEL per
gallon, half the amount of the previous 100 octane avgas (at 4.24 grams per gallon),[16] but far more than the 0.1 gram per gallon permitted in
automotive leaded gasoline or the 0.001 grams per gallon in automotive unleaded gasoline sold in the United States.[17]
