Yeah, make a pipe bomb too, while you are at it. You'll have the ATF, FBI, and who knows who else crawling all up in your ****. A buddy of mines cousin made a pipe bomb and blew it up... The ATF and the Feds were all over him within a few hours, and now he's in the clink doing a 5 stretch.
Either way you slice it Emo man, you're being stupid as all **** doing what you presented. You really want to have some fun with explosives that is somehow legal? Tannerite it up. You'll need your dad (or someone else with a gun) though.
Stay away from the infernal substances, because after you blow your hand off, you'll also be sued by the state and incarcerated. An all around bad situation.
Remember that EMO thread that you made to try and save yourself from being labeled as the thing you want to, yet dont want to, be labeled as? That's why. I thought the very same thing when I saw that you were asking about shotguns.
