You don't have to be so categorical. Yes, indeed, acetone peroxide has a number of problems, the main ones being high volatility, crystal growth and
increased sensitivity, as well as high sensitivity to friction and static. But it compensates for this by being extremely cheap and easy to make. As a
result, it is the best initiating explosive when nothing else is available, and the finished detonator primer is not expected to be stored for more
than a couple of weeks. Although I am generally against storing ready-made detonator caps on acetone peroxide. It is better to store it in powder form
on a piece of paper and not prevent it from evaporating.
The detonation velocity of silver acetylenide-nitrate is 4450 m/s at 5.36 g/mL, and 2710 m/s at 2.92 g/mL. This is slightly less than lead azide, but
it is not correct to compare initiating explosives on the basis of detonation velocity. These substances are supposed to be used to detonate secondary
explosives, and here the area of transition to detonation has a much greater influence than the velocity itself. Acetone peroxide in the form of a
small mound of powder simply flashes when ignited, sometimes with a slight pop, while lead azide, for example, detonates. Although acetone peroxide is
more powerful than lead azide, and in the case of large detonators for low-sensitivity explosives, say 5g, acetone peroxide will definitely be more
effective (but don't do so unless absolutely necessary, given that you have PETN, you don't have such a need).
The difference between silver acetylenide (Ag2C2) and the complex (Ag2C2•AgNO3) is very large. The first substance does not involve any use. It is
much more sensitive than acetylenide-nitrate, can explode already during pressing, much weaker (On a 0.75mm lead plate from an explosion of 1-2 g of
pure silver acetylenide, a weak dent remains, while silver nitrate-acetylenide penetrates it, and the hole is larger than the diameter of the
detonator capsule body), and its initiating properties are lower than Ag2C2•AgNO3 in addition, when in contact with organic substances, it becomes
very sensitive to impact and compression.
While the complex (Ag2C2•AgNO3) is less (or similarly, depending on the manufacturing method) sensitive to shocks than lead azide (from 43 to 79 cm
for a load weighing 500 g), lead azide - 43 cm, mercury fulminate - 24 cm. Also, Ag2C2•AgNO3 is almost similar in initiating ability to lead azide
(for Ag2C2•AgNO3, 0.02g for tetryl, 0.03-0.1 g for picric acid, 0.15-0.05 for TNT, lead azide is almost the same) in general, it does not matter,
you are unlikely to hit less than 0.2-0.3 g, Ag2C2•AgNO3 is stored for a long time, although, of course, it is not as heat-resistant.
NHN is a good primary explosive, but it has its own nuances in manufacturing (a good agitator is needed), plus, like any primary explosive for safe
detonators, it requires proper pressing (from 25 to 60 MPa), at 30Mpa 0.15 g (lead azide 0.03) for PETN. But again, no one usually presses less than
0.2. And you also need the right detonator, that is, you will not be able to fill it as azide, you will need to properly seal it (ideally fill it with
epoxy).

It's hard to advise something if the criteria are unknown. In home manufacture, reagents are still most often needed. From their presence, it
immediately becomes clear what is available to a person. For example, maybe you have silver (or its salts), but no access to acetylene. Then you can
make silver fulminate, it is more powerful than mercury fulminate and less sensitive (if properly manufactured, again). In general, there is too much
to advise.
