I was just thinking, ANFO is not really different than tannerite where you mix it and now you have an explosive. Tannerite is legal to buy, store/transport when NOT mixed, then mixed up and used then and there.
Is ANFO the same? I did some searching, but could not find the answer specifically. |

Lots of things could be mixed with AN

All explosives are legal to make and use federally. Storing them is the issue, well that and state laws.
ANFO is super common because it is so easy/unregulated. Easy to store and transport. |

View Quote Storage, Transport, Sale and state law will be your biggest problems with mixing anything In industry ANFO and other binary is used heavily for since they are easier from a regulatory (storage, transport, sale, state law) standpoint to use. Huge industrial explosive mixer machines exist and tanker trucks that will give you a firehose of gelled explosives to fill your shots |

Well I'm just thinking on very small amounts to be used to Crack up large rocks so my skiddy can move them.
And yes, I'm very rural and these rocks are in the pasture. Thinking drill hole in rock, baby food jar amount of anfo, and work my way up from there if the explosion wasn't enough. |

View Quote There is non explosive rock breaker for that, it is some sort of expanding foam that is slower so it is useable near houses ect. I dunno if babyfood jar size would work, id think you would need a longer tube that was filled so that it will make a "break line" IE they have multiple holes and multiple detonations at same time so it creates a big push at a weak point, im not sure if a hole baby food jar in depth would do that. and very unsure about the detonation set up. Im sure there are actual blaster people here who can give specifics. |

Please just use betonamit or dexpan instead of an explosive. Even some feathers and wedges would be better than haphazardly messing with ANFO.
If you don't understand what you're doing with HEs you're just asking for trouble. Yes you can do what you're talking about legally - but can you do it safely? Do you have backfill or thick rubber mats for tamping and prevention of flying debris? Do you have even a ballpark idea of the tiny difference in force required for cracking rock without launching versus totally shattering it and launching it? What's your planned standoff distance? E-match? Shock tube? Plain old fuse and cap? If you insist on going down this road at least do a lot more research first. |

I wish I could find the US Dept of Agriculture (or some agency) training pamphlet they used to give farmers on how to remove stumps from fields with ANFO.
To the best of my knowledge, binary explosives are not considered explosives until combined and at that point cannot be transported and must be used within 24 hours, so yes it's legal like tannerite within those rules. The challenge being how to detonate it safely, reliably and thoroughly without the licensing to obtain blasting caps/accelerators etc that ARE considered explosives. IIRC the pamphlet recommended using a 1/4 stick of dynamite or something to initiate the ANFO detonation in that training pamphlet so that'll tell you roughly how old it was |

I had a couple bedrock points in one of the lanes that kept catching the box blade, whatever they were attached to was large enough to stop a 60 hp tractor right now. Made slits every inch with a demo saw and one tap with the sledge broke them off below grade and left me with a big pile of stone bread slices. Not real practical beyond about 4 inches though. |

I would say no… “ANFO” is already mixed.
Tannerite is legal to posses and transport by unlicensed people without a permit because it’s binary unmixed, and once mixed must be used or disposed of onsite. Unless you’re talking about mixing the AN and fuel oil on site (like tannerite). Or AN+NM… or AmmonAL… or whatever binary. How are you planning on (lawfully) detonating it though? Can unlicensed people even buy/store blasting caps? |

View Quote So I just do it the old fashioned way. Black powder and cannon fuse. On my last attempts, I got some TiteGroup on sale, so I used enough of that in a hole to blow up 15 fucking pistols. But it just rifled up. Part of the key is sealing the hole. I used to use Rockite, which worked pretty well. Then I tried much quicker and easier "take a tree branch & stuff it down the hole". But at least half of those, the goddamn thing just rifles. Very frustrating. I'm going back to Rockite for capping/sealing my next holes. I think hole diameter may be a factor, too. Back when I used to do a bunch of them, and had more success than lately, I was also renting a big air compressor and air drill for other things, so I could drill 1.5" dia holes deep, and fast. I had much better luck with that. Now I use a rotary hammer with 3/4" bit and it takes forever just to get 10-12" down. I've even thought of ponying up and just renting the big compressor and air drill again, and just quickly banging out the dozen or so remaining ledge spots I have that are fucking up my mowing machinery. Anyway, mowing season is about over, and I've got a million other pre-winter projects, so this will probably get put off again until next summer to get those last spots. SUMMARY: you don't need high explosives to blow up rocks enough to move them with machinery or by hand. Black powder or fast pistol powder will definitely blow the hell out of big rocks and ledge. BTDT. For more power, if your HOLE IS BIG ENOUGH, you could put some Tannerite at the bottom of the hole and BP or TG on top. I've tried it, but my damn holes are too small. I think it would work better with bigger diameter, deeper holes. Oh, and separately, I wanted to get a bag of AN to make some of my own Tannerite. AFAIK, after 9/11 you CANNOT get AN any more. Agway used to carry it before 9/11, but no more. AFAIK, it is impossible to buy, at least in NH/New England, even if you have a farm and a legit use for it. |

Here's a video showing exactly what I'm talking about. These were done with BP and a fuse. Also with Rockite as the hole sealer; I've definitely got to get back to using Rockite instead of pounding a wood plug into the hole. This blows it up enough to get the rock out, but not so much you're in shrapnel danger or having to get a truckload of dirt to fill the hole. In the video, you can see several places I already did, then this video shows setting off the last one in that area.

(Edit: Oops, @third_rail beat me to it!) Guys, a couple of general things to keep Brownells’ corporate counsel from having a heart attack: 1. Don’t mess with explosives if you haven’t been trained in some form or fashion. 2. Look into all Federal laws. Then look into them again. Follow them to the letter. 3. Look into all state laws. Then look into them again. Follow them to the letter. 4. Read and follow any instructions for the explosives to the letter. 5. Establish safe distances with an extra fudge factor for whatever you’re doing. Clear all bystanders, curious people, and livestock/pets from the work area. 6. Start with a tiny charge and work your way up. It’s just like reloading in that you don’t max out at the beginning. 7. Have all necessary tools ready before you go. Double-check that you have everything before you set out. Getting set up to do work and discovering you left something you need at home is a major problem if the explosives are mixed and ready. 8. Have emergency phone numbers written down and ready. 9. Don’t take videos and photos and post them online. ATF has previously called this earning money from explosives, which requires some form of FEL. I believe this got FPS Russia in trouble before he got into more trouble. 10. Finally, when in doubt, don’t. Stop whatever you’re doing and seek professional guidance. |

I recall reading many years ago when I was more interested in these sorts of hijinks, that ANFO was amongst the most difficult to detonate compositions, typically requiring not just a blasting cap but a booster charge as well.

Hello everyone, I'm bit late to this discussion so I'll do my best. I'm a FEL Type 20 and a PA Certified Blaster. I routinely work with ANFO as well as multiple other types of HE. Personally I love ANFO, it's cheap and is a slower HE which makes it perfect for moving earth and breaking rock, but it does have it's issues, such as can't use it in a wet environment and it is not cap sensitive, meaning a #8 detonator (aka blasting cap) will not initiate ANFO. You need a booster charge. In the industry, we typically use a Cast PETN booster anywhere from 90 grams to 450 grams, but a stick of dynamite also works just fine. Now to sent off the initiator charge, we use a #8 Det. The initiation shock needed to detonate ANFO is far higher than that of black powder.
Now, to break rock you want to have the charge inside the rock and this is accomplished by using a "blast hole". If not, you would need ~10x amount of the charge to brute force the rock into cracking. Same thing with knockings down trees with dynamite. You can precision slice a 8" green tree with one stick of dynamite if you have a blast hole, while that same tree with no blast hole would require 3 sticks to brute force if you just taped to the side of the tree. Rocks are the same way. Lastly, commercial ANFO (premixed and typically purchased in 50lb for smaller jobs) is WAY more powerful then home-made stuff to such a degree you can't really compare the two, so keep that in mind when calculating how much you need. In most states and federally, it's legal to manufacture and detonate HE without a license. BUT, you can't transport it, store it overnight, or use it commercially for profit, however many counties and communities have banned the use of explosives for non-FEL's, so keep that in mind. In this Google Drive folder we maintain: https://drive.google.com/drive/folders/1Ts9DTGKJ7j9lO_lbNqP_5ajH5riUgp0x There's a file called HE Gov.pdf that has a wealth of information about explosives and their uses. It's a great read. |

Personally I love ANFO, it's cheap and is a slower HE which makes it perfect for moving earth and breaking rock, but it does have it's issues, such as can't use it in a wet environment and it is not cap sensitive, meaning a #8 detonator (aka blasting cap) will not initiate ANFO. You need a booster charge. In the industry, we typically use a Cast PETN booster anywhere from 90 grams to 450 grams, but a stick of dynamite also works just fine. Now to sent off the initiator charge, we use a #8 Det. The initiation shock needed to detonate ANFO is far higher than that of black powder.
