pure lead

x- ray lining **Should** be pure lead as any additional elements would add cost for no benefit. However the only way to know is to do a hardness test. Lots of kits and cheap DIY's on the intertubes if you're interested.
 
What my "yard" calls "X-Ray" lead. 40#s cut in half to fit my lead pot.





9mm cast and coated bullets for scale.



This is thinner than the 88#s I picked up early this week.

So what would the hardness number be on pure lead? The Lee testing kit I have doesn't show a low enough number to even tell me what pressure I can run with this stuff.
 
That's be cause pure is generally only used by the black powder group. Generally an alloy of 10-12 bhn is what people shoot for. Adjusting for what they shoot and at what speed. A lot of people do a 50/50 pure/coww
 
I'd love to find 30-40 lbs of pure lead. Just starting to cast for some black powder guns and need the soft stuff to get the base to expand and grab the rifling. If anyone has any for sale in the Kitchener/London Ontario area?

So if I use the hardness tester on bullets cast with this pure lead and powder coated, I get a hardness of 11.4. Is that suitable for use in a semi-auto 9mm?

Pure lead should be around "5" BH . you will have to check your boolits before PC'ing. The PC is skewing your results. Even tho you are getting a reading of "11" your lead is still no more than 5 if pure. I have shot pure WW (I don't have tester but should be somewhere "8-10") that was PC'd at up to 1700 fps and no sign of leading in a rifle length barrel.

I wonder if the lead hardness test will work on PC coated bullets? The powder coat may shrink back a bit giving an inacurrate reading?
