I get 12-13 BNH on aircooled clip ons
15-18 BNH on water quench clip ons (aged 2 wks or more)

6 BNH stick ons air cooled (100% lead is 5 BNH)

I use a Lee hardness tester.

Haven't tried water quenching stickies, but according to what I've read the arsenic present in clip on wheel weights give the alloy the ability to harden. LYMAN #48

I don't think there is any arsenic present in the stickies, but it's something I need to try next time I cast my 45-70 GOV. 405 hollow base out of stickons.
