I recently purchased a Mossberg Maverick 12 guage short barrel shotgun.
I got some snap-caps to make sure that the thing worked correctly.  The
thing jammed about half of the time when pumping the shell into the
chamber.  Am I likely to have jamming with real shells (I am planning to
test it for real soon)?  Are snap-caps not meant to be used in this way?
I noticed that they get pretty beat up in this process.

The first difference between the S&W 41 and the S&W 422 is that the first
one is made of machined forged steel while the second one is made of
aluminium (and is probably molded). That makes a lot of difference.

The second difference is that the S&W 41 is an excellent sport pistol used
for NRA (and a bit in UIT) competitions while the S&W 422 is a plinking gun. 
You get what you pay for.

Yes, a nitrate flash is slower burning than a perchlorate based flash
powder. It also has to be very finely powdered in order to work or
ignite with a fuse only. The slow burning is not always a drawback. If
one wishes to have a good, long lasting flash, then nitrates are
better than perchlorates.

Always mix boric acid when using aluminum with nitrates. Barium
nitrate flash powder is known to have self-ignited. That would have
been prevented by the use of boric acid.

>>When making flashpowder, I use to ballmill the KNO3 and the S together,

>powder), it should be emphasized that an explosion risk does exist.

I also use sodium nitrate based flash powder, but no milling is
required. I simply mix relatively coarse Al (<100 um) with sodium
nitrate (about 0,5 mm) using about 10 % excess of the Al. The mixture
is about impossible to ignite with flame, even with a gas torch you
can heat a long time before it starts burning - so it is safe to
handle. A blasting cap is required to set the powder off and the
critical diameter is about 2 cm. I usually load about 100 gram
charges.

The above flash powder gives an long lasting fireball and a nice
mushroom shaped cloud of smoke. You can really see the bright fireball
rise, before it goes off. Also, the air is filled with aluminum
sparks. After the extremely bright illumination, it is hard to see
anything for a while.

I couldn't aggree more.  The Anarchist's Cookbook is total shit.  (At
least the pyrotechnics stuff:  I don't know about the drug info.)
NEVER follow any procedure in the AC.  Find a real chemical reference
first.  A few semesters of college level chem lab are also almost
essential.  Don't try any of this stuff if you don't understand the
chemistry.  Unless you think that 10 fingers means you can spare
a few...

   TBBOM provides a very similar formula, and names the stuff Peroxyacetone. 
   BUT, neither my Merck index, nor my CRC, nor my college organic chem book 
   acknowledge the existence of anything called peroxyacetone, acetone 
   peroxide, dimethyl ketone peroxide, etc. 

It is a kind of ring from acetones. It is sure called acetone peroxide.
It think it had 6 acetones in it. Not formed from acetones only, of course!
Sorry, it has been a while since I saw the diagram..

Acetone peroxide sure is a very powerfull explosive. There are many
hazards in using it. Many other organic substances (eg. inpurities in
acetone) make extremely unstable peroxides. As a thumb rule I might say
organic peroxides should be avoided completely.

Even if your acetone is *very* pure you'll still have a very dangerous
substance. Acetone peroxide is very sensitive to impacts and static
charges. Remember the guy who poured some AP in the plastic bag and
was injured seriously ?

Even manufacturing AP is not safe. The purpose of sulphuric acid is
to take some water in it (released from acetone). That mixture gets
usually very warm/hot. It should be always done in salt+icecrush
bath. Even then it may get dangerously hot. I must say I know a guy
who filled test tubes with ice and went mixing with them to cool it
down.. With very good luck he did not blow up, however.

All in all, I'd say *never* make/handle AP if you're not ready to
be blown up. Better stick to the good old BP instead.

I've found that the siler nitrate resulting from the disolving of a silver
dime works well to produce silver acetylide without any purification - perhaps
the copper nitrate adds to the effectiveness, though the solution remains blue,
implying that the copper is not removed as an acetylide.

An alternative silver salt to try is silver oxalate - add an oxalate to the
silver nitrate solution and it precipitates. This will deflagrate when dryed
and lighted, though it's more amusing than dangerous..

 excuse my ignorance: i only just dropped accross rec.pyrotechnics.

 for a show and theatre performance i need indoor fireworks, smoke screens
 and fire. questions are:

 what is safe (indoors, mind) in the way of inflammables like white spirit,
   alcohol (would probably show not much of a flame?), gasoline etc. and
   what could be added to make the flames more impressive (like'colouring'them)

 what may be used as smoke screen besides stage fog, esp. if black smoke is
   required.

 what kind of firework may be used indoors

 are there any important reference books on this subject?

At a guess, I think they are talking about an arsenic-containing compound
commonly called red orpiment. I don't know the formula for the compound
off the top of my head, but it should be in the Merck index. Don't forget
that the Anarchist's Cookbook is extremely unreliable and shouldn't be
trusted as far as you can spit a rat in a headwind.

Yeah, there were several articles on this years ago in the magazine of
the late, lamented L-5 Society*.  I forget whether it was American
Rocket Company or Pacific Launch Services that was working on this --
they did a number of static firings, including at least one CATO which
resulted in flying chunks of flaming rubber which promptly went out as
soon as they were removed from the spray of LO2.

It sounds like one of many good ideas that nothing is being done with.

C4 (the end of a developement up from C1 in WW2) is a plastized Version
of the very brisant explosive Hexogene. One may produce it by nitration
of Hexamethylenetetramine (which is, for my information, the main contents
of the US Army Sterno / Dry Heat (or whatever its name is)) and plastizing
it somewhat via oil/glue ...

I wonder if this is true.  From what I remember KNO3 and S curiously
will not even burn or ignite together in any way.  I believe you need some

Maybe you should try using gas welding goggles? It should still look

Do you need much confinement when using a detonator with this mixture
and is it very loud. (Don't want to alarm the neighbours..)
