I have found this to be accurate by measuring the harness of both bullets before loading , which could be months after casting, and pre mixed ingots , which could be many months after smelting (I premix quite a few kg using commercially pure lead and tin). FYI I use the Cabin Tree tester (see here: http://www.texas-mac.com/Evaluations...s_Testers.html ) which is now made by this bunch: http://cowboybullets.com/Lead-Tester_p_57.html

Very interesting, thank you.

I like that Cabin tree tester very much, particularly as it seems to be able to measure run out as well...
