If you wish to take this discussion to a personal level, then yes, I think a private individual making exploding projectiles is stupid in the extreme. I'm certain that there are some who have the background and training to do this safely, but you do not say you are one. There is no practical application for an exploding projectile other than to be able to say "HEY YA'', WATCH THIS". However having spent 31 years defending your right to say, think, and do as you please, I don't say don't do it, I simply say in my considered opinion the practice of making exploding projectiles is in fact pointless and stupid.
If some kid reads your statements and subsequently get injured attempting to duplicate what you have done, it’s on your head.
