Rules about tracers.

[Targan]

Most of my experience with explosives has been as a civilian shotfirer (powder monkey) but I have been reading this thread with great interest. I agree that the burn time and reliability of most if not all chemical fuzes will change over time.

The biggest individual charge I ever set off was just under 30kg (mostly ANFO with a few kilograms of Powergel primer charges) and that produced a pretty darn impressive explosion. I've set off more than that in one go as part of a team but not all in one explosion (coordinated timed charges with quarter and half second delays between each blast). And det cord is great fun.
