[QUOTE="MagnumManiac, post: 2969892, member: 10755"] Original tension varies by manufacturer due to alloy content, HOW and WHEN it is annealed by them…not all manufacturers anneal as a last step. Some anneal prior to every forming, but do not anneal again after final neck forming is done prior to tumbling. A few manufacturers anneal less during forming, then anneal as a last step. This changes final hardness, and annealing yourself is most likely going to be different than the hardness the manufacturer adheres to. I ran several brands of cases through a Rockwell hardness tester, not one of my annealed cases matched their hardness, all of them were less… Cheers. [/QUOTE]
