I just picked up some single shot double break no. 500 mortars. No odea what kind of bang I'm looking at here aside from assuming there will be two bangs. How are these things rated? I'm guessing 500 has to do with the powder but is that just the final bang? If it's a double break does that mean 250+250 or 500 each? 500 grams is the largest amount of powder any single consumer firework can have. What manufacturer? There is probably a video of it on you tube. |

rule of thumb is 100 feet of clearance per 1 inch of tube diameter.

I'd test fire one but I'm in a subdivision right now and I've only got 8 shells. Gonna test fire one tonorrow at my sisters place. |

Edit You're not going to get a single shell that's 500 grams. Those are kick ass multie shell/tube repeaters. No need to test Fire. Treat your mortars with much respect. Light the fuse and run away. Make sure the shell slides easily into tube. If it doesn't. Stop. Keep spectsrors far away. The break on the explosion can be 200 feet plus You don't want one breaking 20 in the air with spectators 50 away. Ask me how I know. Treat them with serious respect and be safe. |

Of course they didn't bother and after the first shot the rack, predictably, tipped over and they were dodging 2" shells.

Been hunting down videos of the fireworks I picked up this year, since its the first year we can legally set them off at a site here. Figure that.. Pahrump has 4 fireworks stores and we could buy them but not shoot them off.. anyway this year that changed.
I picked up a few of these, they are 500 gram double break shells from Winda. Here is the video I found of them.. not my vid just a random one. https://www.youtube.com/watch?v=hK0XeMQdaHM |

Another safety tip.
Do NOT position yourself over the tube when loading in a new mortar. All it takes is one ember to burn through that thin paper at the bottom of the lift charge and you're eating a 2" shell. |

Doesn't cover anything I don't want destroyed. Like my face or hand. Regarding a base. If you don't have ample concrete then get some very sturdy base for it. If your base is grass you're asking for very bad shit to happen. |

To be honest I've never measured a typical #200 tube. Besides I thought limits were based on content rather than size. You can go on phantoms site and they have 3" tubes listed. Either way I can assure you they were consumer grade |

The pyro was protected, but the humidity got into everything. Had them going off in the tubes, low breaks, weak charges launching a 6" salute only about 200' up and having it land a whole 20 feet in front of us THEN bursting. Fucking nightmare. I still have the T-shirt I was wearing when I was hit by a star in the chest. Good times. Posted Via AR15.Com Mobile |

Since we are throwing out safety tips. Do NOT use pvc as a launch tube. It becomes shrapnel if there is a mishap.
HDPE, fiberglass, or the heavy cardboard only. |

I generally shoot 2.5 and 3" mortars. 3" being the max safe size for your typical "yard show" IMO. I cordon off a 150ft circle to keep things safe. Never had an issue. I place the tubes in 5 gal buckets anchored with sand. Love the 3" they pack a MEAN blast when they exit the tube ! The mortars I buy have both the electronic and the traditional type fuses. You need to be on your game when you light the fuse as it travels at 2400 fps ! I have 16" long grill lighters so I can keep a safe distance from the tube. Anything bigger than 3's I think will just draw too much attention from the po. Keep it reasonable, keep it safe , and keep it going for years to come. Had a bad situation in my town several years ago from a large 4th party (not mine) that got out of control and a couple people got seriously burned. Excessive alcohol was a factor... be cognoscente of your surroundings and be safe !

here is some info on the #500 Preloads.
http://www.pyrouniverse.com/forum/showthread.php/40867-500-shell-vs-artillery-shells basically a 2 3/4" shell . most of those 9 shot "3 inch cakes" have 9 of these shots in them. there are no True 3" consumer fireworks. that #500 is that largest consumer FW available legally I would not pay phantoms pricing for those even at buy one get one. . here are 24 slightly larger single shot tubes in a case for a much better price than phantoms. http://www.76fireworks.com/fireworks_videos/Tubes/TB106_100_Brothers_Assorted_2_38_Shells dont get too caught up in the "numbers on the tubes" there are many versions and Most Manufacturers use different lingo for some of the same things. u will see many single shot tubes called #500 #300 #5 #100 and so on. |

It's your call to make, but if there's an accident your insurance company might get snitty. As for fusing, if you are using the paper-wrapped type, you can slow it down by stripping the paper off. |
