I was surfing on Utube today and came across a video of a fellow that had a method on how he checked the hardness of his case necks before and after he annealed the case. I am always seeing comments and videos on how to tell whether you got your cases annealed to the correct temperature but nobody can actually say whether they got it right or not. Some of you might have seen this method before but I hadn't so I thought I would post the link to the video. Go to the 22 minute mark and that is where he starts to talk about how he checks his cases to see if he got the correct annealing temp. He shows a PPU case with a hardness of 17 and then anneals it down to 13 hardness so he knows that it was annealed correctly. You have to check each brand and lot of new brass to see what the hardness is so that you can anneal it long enough to get it back to original hardness.
This is the W-20B Hardness testing tool and it has a 6mm(.2362) shaft so 6.5 case necks should fit on it without modification. This one is about $375.00(shipped) and it is a cheap one but does the job.
Here is the video if you are interested:
Update: Shows in more detail how he is checking the neck hardness:
Just thought this was a way to check for sure if you are getting your cases annealed correctly.
Edit: The annealing machine that the fella uses is one that he built himself. It is a pretty neat piece of equipment.
