I should know this but I don't. Help me understand the difference between some of these verbs I am reading because I am sure there are differences between "burn", "explode", and "detonate". Timb99, you are saying that with enough heat, the powder will burn with enough force to burst the casing? I would think the primer would have already exited under a lesser temperature, also? I would guess (LOTS of emphasis on "guess") that Physics would say that, given a choice between the bullet going forward (ish) and the casing propelling backwards (ish), because the bullet is so much heavier than the casing, the casing would depart in whatever direction first?
I just don't have a good mental, visual picture of what would actually happen under the old "bullet in the furnace" in Wood Shop class scenario.
