I have not posted to this group for several years, so I am largely
unknown to the group. I have been spending most of my hobby time and
money building large fireworks. I came across a formula for
exploding targets. They need a hit from a bullet in the 2000 Ft/sec
range to explode. Current US explosives laws require you to have a
permit or a license to possess, store, or transport explosive
material. The law does permit a person to make explosived for your
own use, if you use them the same day and do not transport them. You
must also make sure you are not breaking any state or local laws.
The formula is described on this web page,

This is not my web page, but I have followed this fellows methods to
make my own targets. The ammonium nitrate is a specific type of
fertilizer and often people do want to know what you are going to do
with it. If you know someone that raises crops, you might get some
through them. The potassium chlorate can be obtained through pyro-
technic suppliers like Skylighter (www.skylighter.com). Please read
all the cautions on the web page. This stuff is not spark sensitive,
so you can't set it off with a fuse. Also, a 22 rimfire will not
work...I have tried. Actually I have been working to make it
senstive enough for a 22 rimfire, but it needs more energy to make it
blow. When it does go off, a 6 oz yogurt cup is similar to half a
stick of dynamite. It makes a large amount of white smoke and a good
boom. It is idea to see if you hit a target. It is good for
practice shooting when no real varmints are available.
