What is a "grade" exactly
- I'm working on something and the construction says to use a "grade
3" Blasting cap. having no access to such a thing; could anybody
tell me a proper sub for it. Also if anybody knows about what
a "grade" is equal to, I understand that it has to do with the
ammount of energy required/produced to begin a reaction. But beyond
that I am clueless...

I've never heard of such a thing. I did a Google search on the term,
and got two hits: they were total BS (from people who were probably
so-called "teenie-bombers") containing various errors. Blasting caps
are normally designated by "number." A number 6 cap is the most
common for civilian applications. Military explosives tend to be
harder to detonate, and use higher number caps, like 8. And there are
no standard caps less than a number 6.
