I purchased 500 lead boolits online several years ago. They are 45 cal. 230 grain round nose tumble lubed. I checked the hardness on 3 boolits and they average 20 BHN. I load midrange loads for my 1911 and almost always shoot suppressed. Should I use these boolits as they are or throw them in my pot with an equal amount of soft lead to get a hardness around 12-13? I just started casting the same boolit using range lead and hardness averages 10-13.
