[ARCHIVED THREAD] - Exploding bullet? (Page 1 of 2)
Posted: 5/19/2011 7:40:12 PM EDT
New level of dumb. A maintenance guy on a job I service tells me his dad says that a guy can take a .50 cal round, say maybe 300-450 grains, that has a soft tip, and drill it out so a .22 long fits into the large bullet but backwards. Thus, an exploding bullet. 
My reply was that one would need a drill press to make the hole perfect or it would never be balanced. Second, nothing great would even happen. Ever hear of this? My last word on the subject was that it was a retarded idea, and may even be illegal. |

You had to even ask?years ago, i had a deputy sheriff give me a few 'exploding' bullets. i still have some. these were 38 special steel jacketed hollow points with a primer inserted into the hollow center. i have no ideal if they performed any different from a normal hollow point. |

I have indeed learned new and very odd things from this site, and just when something sounds too retarded to be true, someone has in fact not only done it, but it was awesome. I doubt this is the case here, however. |

The Devestator round in 50 caliber, interesting.
I believe the Devestator was used to shoot Reagan, and most did't work as designed ETA: Correct spelling is Devastaor, info about exploding bullets |

It's actually not a new idea. Some of the African professional hunters experimented with doing similar things in the black-powder cartridge era. As I recall, it was attempted to make very large (as in 8- and 4-bore) bullets expand, explosively, as you might imagine. There was an article about this in the Gun Digest annual some years ago. Now in a .50 BMG? My question would be, why bother?? |

oh lord... dumbest idea known to mankind.
people only post this shit to see if it's possible and, if so... is the effect cool. a "friend" told you about this... uh huh. riiiiiight. theoretically possible, but the effect would be like watching a balloon pop from hundreds of meters away. -rb |
| I put a drop of mercury in a 9mm hollow point and seal it with wax. I've taken many water buffalo along the Guadalupe with that load. There's nothing left but a hoof and a set of teeth. The rest is all exit hole. I shoot a lot of VC that way too –– got two just last week. |

I've heard people describe modified 12 gauge slugs the same way - either a 22 short is inserted bullet first into the hollowpoint, or the hollowpoint is drilled out to accept it. Theory is that impact will obviously detonate the 22 short round, causing an "explosion". While that might theoretically be possible, sounds like a good mythbuster situation.
The above definitely not as effective as .50 BMG APIT rounds in terms of destruction, incendiary capability, etc. Years ago, a high school buddy liked to play around with improvised explosives - mostly blackpowder based but sometimes more extravagent like perchlorate powders in vaseline, set off with no 8 blasting caps. Most of his improvised stuff was duds including one device he'd built with black powder and probably a couple hundred 209 shotshell primers, although the one detonation I witnessed of perchlorate powder mixed with vaseline and touched off with a no. 8 cap was pretty frigging impressive to a 17 year old (myself at time). Don't know how he managed to never blow himself up with his experiments, he seemed careful - but this was pre-internet days, and mostly based on those old copies of the supposed WWII guide to improvised munitions (never did know if that was a real gov. manual or not). |

Damn. Should I suggest where to shove your post? Yes, I actually was curious if anyone had heard of this, but I sure as hell don't sit around and daydream up ways to stick bullets in bullets.
Agreed with your last line, but the middle line is a dick comment.

I was thinking it would need to be moulded into a lead bullet. Molded in would work (if it didn't detonate the .22 in the process), but you could drill a bullet and do this if you were determined enough. You could set up a fixture of some sort to hold a bullet while you drill away the tip and part of the core, then insert the .22. You'd need a good drill press (or mill), good tooling and a well made fixture to do it. If you had the resources to pull this off, you'd also have the resources to make an exploding bullet in a better way. |

Quoted: You'd need a hell of a lot more than "just a drill press" to pull off that kinda op. Naa, you could do it just a coaxial indicator,dial indicator, and a drill press. Chuck the drill bit up in a vise, or some other holding tool, then put the coaxial indicator in the drill chuck. Sweep in the drill bit, then swap the coaxial indicator for the bullet, then true the bullet tip up in the drill chuck with the dial indicator. |

Molded in would work (if it didn't detonate the .22 in the process), but you could drill a bullet and do this if you were determined enough. You could set up a (precision) fixture of some sort to hold a bullet while you drill away the tip and part of the core, then insert the .22. You'd need a good drill press (or mill), good tooling and a well made fixture to do it, but I still think you'd have some trouble keeping it all consistent enough for good accuracy. You may have issues drilling the bullet without destroying it. If you had the resources to pull this off, you'd also have the resources to make an exploding bullet in a better way. I have no intention of modifying anything but I agree that it could not be balanced. Just not worth the effort. As for moulded in, I meant a cavity....like a hollow point mould. |

No other Internet forum. Not sure where you got that idea. Let's recap, shall we? 1... This was based on a conversation today, a follow up to conversations earlier in the week with the same guy. 2... I have no plan to even attempt this, as it just sounds retarded. 3... I was genuinely interested if anyone had heard of this. Most of these rumors or ideas have been around for a while. 4... Not my friend. Maintenance guy at an apartment complex were I service the heat. Any further questions? Can I be any more clear? Please, feel free to ask. |

Am I the only one on this list that ever heard of a lathe? It wouldn't be hard, but it also wouldn't be smart.

Again, FWIW, I really do not believe any real reaction would occur. I would be more concerned with the .22 going off when the gun was fired.
Actually, odds are nil it would go off when fired, and almost that upon impact. If the target was hard enough to pop the primer, it would cause the bullet to come apart faster than the .22 round could do it. No point unless you were shooting it really slow. |

Isn't that the truth. At work we do rough fab (not me), and it's hard to find anyone that can run the machines. It's all manual, since every piece is a "one off". I can, but I make too much (management) to put on the job. ETA: 48 years old here. |

Tell him his idea is stupid and they have new bullets that are way better then that stupid idea. Including newer inferno bullets that will set a small fire inside a person. Have him watch this video.

Shame we are getting kinda slow in the lathe depot right now and that's my section so I may not have a job soon:-( Sucks because we are a firearm mfg and I can bring my personal weapins here and clean them etc if I like. Getting worried!!
The biggest complaint I have with our shop is no damn digital readouts. Ever move a flatback magbase indicator 10 inches, 2 inches at a time? it sucks. I was always have been the youngest up until now:-). I started my career on manual machines and it was fun but hate spending all day on one part lol. |
