A couple weeks back I came across and old post using the search function, I wanna say it was in 2011 of the post. . .now I can't find it. In the post it talked about the chart that comes with the Lee tester for the given readings not being "totally spot on" and one of the forum members did a more extensive series of tests and came up with a more accurate chart. Then another member in the post checked the new chart numbers and he agreed that the new hardness chart was definitely more accurate. He also offered to PM anyone the re-calibrated chart. Does anyone recall this post. . .have the revised chart or can point me in the right direction. I feel my Lee Tester is good/close enough for my hobby, but curiosity is getting the best of me and I want to do a comparison of my own. Thank you.
