[QUOTE="fishdundee, post: 2854121, member: 67916"] I'm curious about flame temperature. I just ran out of the old MAPP gas which had no problem getting the brass to glow. I would anneal the same as Cortina would to where the brass would just start to glow and it was done. I purchased some new MAPP gas which is now MAP/PRO and the flame temp doesn't get as hot as the old MAPP gas. After some research , I tried some Bluefire mapp gas which is said to burn as hot as the old MAPP gas. It's close but not quite. So in all my 53 years of infinite wisdom, I purchased a torch and oxygen to run with all these little yellow bottles of mapp gas that I now have. The flame on this torch is very small and easy to control and as you might have guessed....Way Hotter. Depending on how far I hold the flame away from the brass, it takes about 2 seconds and the neck starts to turn to a dull glow. I don't get the heat transfer down the case like I used to do with the old MAPP gas because it is so quick. I've just started doing this and so far my results seem to be the same as annealing my old way. I definitely have more testing to do with all my other calibers. I only tried this out of my being to cheap to step up to an AMP annealer. Has anyone else tried this way of annealing brass? I should add that I spin my brass in a socket chucked up in a drill with a vice. [/QUOTE]
