Introduction: Detonators (Blasting Caps)

Detonators (blasting caps) can be made from a used small arms cartridge case and field-manufactured explosives. Detonators are used to initiate secondary high explosives (C-4, TNT, etc.).

This destructable was "borrowed" from The Army's Improvised Munitions Handbook, courtesy of Steal This Wiki.

As the views break 2050, I would like to thank you all for reading, it makes me feel useful. =P

Be sure to read the warnings.

Step 1: Materials Needed and Primer Removal

Remove fired primer from a used cart ridge case using a sharpened nail.

Step 2: Drilling

If necessary, open out the flash hole in the primer pocket using a drill. Make it large enough to put the fuse through.

Step 3: Fuse the Cartridge

Place one end of the fuse in the flash hole and extend it through the case until it becomes exposed at the open end. Know this and then pull the fuse into the cartridge case this preventing the fuse from falling out.

Step 4: Loading the Explosive

Load the primary explosive in the cartridge case. Use the following chart for the proper amount. A handbook page is a piece of paper.

Step 5: Compression

Compress the primary explosive into the cartridge case with the wooden stick and the following improvised loading fixture.

Step 6: Booster Addition

Add one gram of booster explosive. The booster can be RDX or Picric Acid.

Step 7: Booster Compression

Compress the booster explosive into the cartridge case with wooden stick and loading fixture.

Step 8: Filler

If the case is not full, fill the remainder with the secondary explosive to be detonated.

I am only investigating the use and information about blasting caps for a script I am presently writing. I needed some background info on the things. I have no intention of setting my own explosions EVER. Thank you for the information.

How would Flash Powder work for detonating secondaries?

I would also like to know if black powder or smokeless powder could be used as a primary explosive in the cap.

no it can not u need a more sensitive hex peroxide mixture

i think all it has to be able to do is ignite the booster and your g2g the use for balsting cap is to ignite a substance that need a hotter burn that reg black powder cuz most fuses use black powered

thanks i just made a batch of plastique and am in need of caps

sweet how did u make that blasting caps are easy

This is insanely dangerous! Basically, you hold a metal cartridge in hand while you ram HE's in it? I didn't know military don't like to have their fingers. It's a chance you posted it only for informational purposes. But, I wouldn't be surprised if some k3wl went and tried it. Darwin Award!

its like packing a black powder rifle
