You don't need a lead hardness tester for lead bullets shot in a 45 ACP. If you made an alloy of 1/2 WW and 1/2 lead pipe, you'd have "soft" alloy, but not too soft for most handgun bullets. Prolly run about 9-10 BHN. Remember, harder ain't necessarily better. More important is bullet size. For your 45, .451" to .453" will be ok and if you slug the barrel run bullets about .002" over groove diameter. No experience with 10mm, but I've used straight wheel weight alloy with hefty .44 Magnum loads w/o any leading.....
