[QUOTE="Coyote Shadow Tracker, post: 2716593, member: 116439"] This is why so many people will not answer Posts on annealing. There are so many different views and opinions on the type of annealing and machines used. Brass is Annealed between 500 & 800 degrees F. Depending on the type of heat used will depend on the length of time to heat at a specific temperature-AND for a specific Purpose. Brass is composed of 67% Copper & 33% Zinc. Brass Cartridge Manufactures may have their own Proprietary percentages of Copper, Zinc and possibly other metals. Zinc Melts at 780 degrees F and Copper 1,985 F. I am not a Meteorologist, but have worked for General Dynamics Electric Boat Division Nuclear and studied Metallurgy and the effects of heat on metals. There is the "Window" of "Heat Temperature" to Properly Anneal specific metals. If it is under the specific temperature for a specific time it is not Annealed. If it goes OVER the specific temperature the molecular structure of the metal can change - also will not be annealed properly. The metals (Copper/Zinc) changed past their original specifications. Proper annealing will help your BRASS last for more cycles of reloading. What I posted is just a fraction of information that you can get on "Cartridge Brass Annealing" You should do your own research to make the determination on how YOU will PROPERLY Anneal Your Brass. We have used and tested several Brass Annealing Systems and found one that works best for us. I know that one of the reasons for LRH is to get information to help you reload and save you the time to determine what is best. Annealing is one that you need to research and pick the best for you and your budget. Most different types of Annealing Machines will give you the same results if properly used. [/QUOTE]
