Mercury tipped bullets?
First of all, mercury is poisonous. You should not handle mercury without some form of protection. It is normal for hollow point bullets to have a cavity in the tip, the question is how do you keep the mercury there while being handled, loaded, shot, etc.....I'm sure there has been a movie or two showing how this may be accomplished using something like sealing wax to keep it in place. There is no question about what it would do upon impact though. Mercury, although atomically lighter than lead, is more dense than lead. When the bullet hits an object, the lead part will slow down faster than the mercury, thus allowing the denser mercury to penetrate AHEAD of the lead bullet. Have you ever played with mercury? Dropped it on the floor? When mercury strikes an object, it breaks up into smaller bits. The heavier the impact, the more bits it breaks into. Essentially what it will do is act like a small shotgun blast ahead of the bullet, perforating the tissues ahead of the bullet and allowing deeper penetration and slower expansion. I have never seen the actual effects in ballistic gel, but I would think that the overall cavity left behind would be smaller because of those facts, negating the desired effect of a hollow point round which is rapid expansion and energy transfer to produce a wide cavity rather than a narrow, long cavity. And then you have the mercury....at that small size, it would be near impossible to remove and it would probably be mostly absorbed or oxidized by the body. I am not sure what the LETHAL dose is for mercury, but since they used to inject it as a treatment for herpes, I doubt that a drop alone would be fatal.
Where can i sell or dispose of liquid mercury?
I have about two ounces of liquid mercury in sealed glass that I've had since my husband died and would like to be able to sell it if possible, otherwise where would one dispose of such a thing?
