Been casting for just a year or so, and have accumulated a few molds, including a Lee 148 tl two cavity and an old Lyman single cavity 358425 for 112 grain boolits. I have clean lead as well as coww's and casting them using 50/50 lead to coww's. I keep velocities low and load target velocity in snub and 4" 38's. Am I ok to cast in pure lead or maybe use less coww's? Maybe a 75/25 mix of lead to coww's or even less? Cast pure lead wadcutters ok? Tumble lubing w Lee liquid alox and also Emmert's pan lubed at times with the little 112's. Trying to conserve the coww's I have for some hotter loadings. Using red dot and tg powders for this. Looking for recommendations from your experience. Thanks for your time and help on this.
