I have plenty of experience with old Ideal molds and Lyman molds but I have never purchased or used an aluminum mold. I recently purchased this mold and noticed the scratching in two of the cavities and then more concerning was what looks like erosion around the edges of the cavities or maybe lead deposits... or I'm nuts and the mold is fine. I know I should cast with it and see what it drops but I am worried if I "use" it I will potentially worsen the situation and not be able to return it if needed. Please smack this aluminum mold newb with some knowledge. Thanks!
