I shoot in an indoor range that has a steel backstop that is angled upward where the bullets slide up, rattle around and slide down into a bunch of long cans. Being as new to casting boolits as one could be leaves me with a bunch of questions. As im looking at the piles of range scrap with all the small pieces of jackets and such, I find a lot of clumps of lead that crumbel in your hand. I guess that is dust from .22 rounds. Is it a good idea to melt these lead clumps or just the larger pieces of lead that I hand pick out. There is no paper or other debris in the scrap, The range is 80 ft and most of the people shoot at 50 ft. This is a fun hobby that lets me shoot a lot more but im just starting the learning process. Thanks Tom
