Hey, guess what the company uses to perforate well casing.

Aw, but I'd rather be creative.

RDX?

Akshully, C-4 is nothin' but a stabilized, safely handleable/moldable form of RDX. RDX by itself is pretty unpredictable - not a lot more stable than nitroglycerine (to which it bears a strong formulaic relationship). I dunno fer sure, but I don't think there's much commercial - or military - application for straight RDX anymore. Could be wrong about its current market status, but I'll guarantee ya there are smarter places to be than anywhere near RDX.

I dun'no what the stuff is, but they segement the tubing cutter charges so it ships as a class 1.4. If it were factory assembled, it would have to be 1.1, if that makes sence.

cant say, the only CFR?DOT numbers I know are for crap we cant carry on a plane.
Most casing cutting Ive had done was always strait dynamite, nothing fancier cause the energy would be wasted by shooting out the casing and everybody'd have to run or get bonked.
Only saw that happen once and it was startling watching a 10 inch mild steel casing 80 feet long come rising out of the ground and topple over onto a service truck. It flattened the truck bed even with a 1000gal water tank on it.

As I said, fm - I dunno fer sure about RDX's place in the market. I do know what its made of, and how to make it, and I know it (Cyclotrimethylene Trinitramine - C3H6N6O6 ) is the primary (like, more than 90% by weight) component of C-4, along with di(2-ethylhexyl) or dioctyl sebacate as plasticizers and polyisobutylene or dioctyl adipate as binder, along with a small volume of ordinary medium-viscosity motor oil and the requisite taggants. If yer gonna be close to a hyper-explosive, its a lot smarter to be close to C-4 than to RDX. To detonate C-4 takes a bit of doin' - not much, of course - simultaneous thermal and kinetic shock of sufficient magnitude will do it - but its lots less touchy than RDX. Of course, once the reaction begins in either compound, there's a much greater distance to go to be sure of safety; if you ain't already there, you ain't gonna make it Mr. Green

Saw a neighbor once get a little overly generous with some ANFO he was usin' to clear some pretty substantial tree stumps. I figure the stump involved hadda go better than a ton. It and a buncha dirt went way, way up. When the stump, pretty much intact and still trailin' a buncha dirt, came down, it picked for its landin' spot the exact spot on which the guy's pickup was parked. Sorta like a cartoon, only live action.

If a roadrunner hadda popped in and gone 'beep, beep' it would have made it perfect....

Guncotton. Anyone can still make guncotton - it's just like cellulose soaked in nitric acid, isn't it? Does anyone still use it anymore?

Nothing about trinitroiodide? Easy to make from household materials and as stable as a cross-eyed look.
