The firearm thread

I've done a bit of fencing so I sincerely hope that this will only be tried on your own personal strainer posts...

Plenty of trees in the bush, as well as possums!

I hear a hollow point .22 with a plastercine sealing cap over some mercury will cut a strainer post in two....

I heard that regular mercury destroys your bullets before you can fire them, and the other kind of mercury will explode in your barrel from the temp....

grease and a small ball bering works, but makes it a single shot

Mercury reacts with lead?

[wbks]

According to almost every google link that pops up with a search of "mercury tip bullet" , regular Mercury alters the bullet structure, and the other kind of Mercury (apparently) explodes at so and so degrees so it would happen before it leaves the barrel. Of course, I've never tried it. Have you?

No, but most metals don't react with other metals.

I could be wrong.

If you're talking about mercury fulminate then that is an impact explosive that used to be used to make primers if I recall correctly...

Don't assume that just because a bullet is being propelled by burning gases that it comes out of the barrel hot, though...

I just had a quick look around and didn't seen anything near 'almost every google link' saying anything of the sort. Some appear to be people with no actual knowledge arguing over whether it is possible, the rest appear to have nothing to do with elemental mercury in a hollow-point bullet. The only single post in the first 10 results decrying it was from an authors blog where the sole reasoning appeared to be 'what the hell you idiots, mercury can't explode'. The argument appears to be centered around the effective 'expansion' of the dense liquid mercury under the compression of bullet impact, not an explosion as such.

The reaction effect you are talking about would appear to actually be amalgamation. Mercury would create an amalgam with lead and therefore harden, but it would be trivial to use an epoxy or something similar to keep the 2 elements separate...

The fact that most reference the JFK shooting should raise a few red flags as to the qualifications of the discussions participants...

Mercury is deemed a "mechanical explosive" as it vaporises readily and expands a great amount in a short time. It will vaporise on impact if used in a projectile.

I haven't done it, but a friend of mine allegedly did. It seemed to work quite nicely on strainer posts, he said.

That fits with the descriptions I read about it splitting railroad ties...

Ordered dies, shellholder, projectiles and primers for the .44 magnum, still need a length gauge so I can trim up some of these casings and a better source of projectiles...

Anyone know of a decent source for casting equipment? Asked at Reloaders last time I was there and got brushed off even though they said they could get it in...

Here is an interesting fact for the day. Winchester Super X powerpoint .22LR rounds will shoot straight through a VL Commodore when shot side on in the boot from a close range.

I bet the VL owner wasn't none too pleased....

(Wasn't yourself, was it?)

Refixed the pictcanny rail thing on the .22, and used some loctite this time.

Who would of thought a few hundred rounds would of vibrated anything loose?

Odd... We had an old car lying around that we shot up a bit, the .22 rounds were making it through the outside of the door panel but getting stopped somewhere inside the door... Went through the windows pretty easily though, although we didn't try the windscreen...
