Hardness testing
« on: June 02, 2011, 07:54:28 AM »
My new Lee hardness tester was waiting for me when I got home and I immediately ran to my man cave for a 'speriment!   ;D

First, my ingots of WW's sweetened with a little 95/5 solder came in at 9 BHN.  Right where the charts I have read said they should be!

Next up was a bullet cast from the aforementioned ingots and quenched in water.  It tested out at just a hair over 14 BHN!

So I learned that my tests confirm, in a general sense, what I have read and heard.  I also figure that once I know the BHN I can make a SWAG as to the makeup of an alloy using an alloy/BHN chart.  Whatever, I'm having fun!   ;D

That scope is real hard to use though...  :-\  I think I'll make a stand for it like I've seen people do on other forums.

I have been "toying" with getting a tester from Veral.  Pricey but stipulated as reliable and easy to use.  I too would like to know where my 50/50 Pb-WW ingots and air cooled boolits lie on the BHN scale. 

So far, cast alloy boolits, powder charge, and lube are shooting well and without leading in my formerly dang-quick-to-lead Ruger Blackhawk Convertable 45 ACP/Colt with Ruger-hot hand loads.  It used to spit lead shaving back in my face.  REAL scary.  Now it is a pussy-cat by comparison spitting red hot lead down range - only and without leading the barrel to a smooth bore after a dozen rounds!!!  I like that and am having FUN FUN FUN!

  I also was interested in testing my ingots. But I was told on CB that because of the larger size of the ingots. The relation of the 2 BHN's would not be the same. I do not know for sure, just what I was told.  Kevin

Another vote for the cabine tree hardness tester....  Tried several others (including the lee) and couldn't get consistent readings....  No problem at all with the cabine tree....
