commercially available tungsten bullets
http://www.gunaccessories.com/Speer/African%20GrandSlamRifleBullets.asp
but at US$140/25 look a bit expensive.
I think a 224 dia tungsten in a plastic sabot would lack weight (energy) of a well constructed hunting bullet.
a 7mm Rem Magnum using a bullet designed for large heavy game such as:
I used to shoot up VW engine blocks just for fun. VW's have magnesium blocks that give off nice sparks.
An ordinary 270 and 308 will punch neat holes thru 10mm mild steel. 55gn 22-250 will punch a hole in 5mm steel, but embed in 10mm.
If you went for a 338 or better, it will take a lot of steel casing to stop it getting to the camera.

spray paint, low cost and easy to apply

Do you know that movie?

No, unfortunately. It's interesting though that such nice and timid people like the Swedes destroy these things as often as they do. This happens on a regular basis.

I like Litigious's style and blowing them up.

Me too except I'd like something longer ranged like a big .338 (Lapua, Lazzeronni or Weatherby)
Or maybe a .404 Jeffery or a .378 Weatherby
But then again comes that problem with getting the gun in this country. The chemicals for homemade explosives are completely free to buy though.

Gimme a Barret M95 .50 BMG at sixteen hundred yards - that'd do the trick.

Are barrel blanks regulated in Sweeden?? If not, there's your ticket!!
Find a good machinist (or do the work yourself if you know how) and have them make a receiver and all the necessary parts that can't be bought.
Pesonally I'm a machinist in the racing industry so this would'nt be a problem for me. Just as long as I have blueprints for a receiver, I'm good!! !

Thats why the saboted double hemisphereic cone would be usefull an unrifled steel pipe
could be used because the shape of the projectile stablizes it.
I saw a Barret .50 BMG at gun shows 10 years ago(last time I went to a gun show) they
where several thousand dollars at the time.

So infact a smaller .224 tungsten bullet could equal a larger .308 round lead/copper jacket. Because Tungsten is so heavy. A lighter bullet could in theory have a higher
muzzle speed and equal a heavier slower bullet in energy. Not sure when the sweet
spot would be. But from a practical point low cost copper jacketed harden steel is the
normal AP round. Energy = 1/2 M X (V X V) so you can see how going a little faster
makes a big difference because that value is squared. .

I expect sectional density plays a big part (weight of projectile divided by its cross section area). IGiven chamber pressures and recoil are limiting factors, in a copper jacket lead bullett, 7mm or 270 is about best. Not sure how other metals would stack up.
Nice research project

But also need a ladder and approx 5 - 15 minutes hanging about the immediate vicinity of the camera.
Hi powered rifle, don't need to get closer than 200m.
