Right - the cases are indeed very, very, very big heat sinks. Especially the aluminum ones (the studs really only break in the aluminum ones, so you wouldn't normally use a torch on a mag case). You can place a propane torch on an AL case for about 15-20 minutes, and it will just about get hot then. You can't do much damage with the propane. The oxy torch, however, you can indeed get carried away with. Use your head - don't do anything stupid...
