Questions. I’m interested in casting for 300 blackout (110-150ish grains) for possible hunting whitetail and coyote. Does anyone know what mold would be good for a 30 cal boolit in that weight range? Please excuse my ignorance, I haven’t actually started casting yet but I’ve just about got all the stuff I need-Lee production pot, few molds, small amount of lead. I’m wanting a super-sonic load around 2000 FPS. Would that velocity need gas checked? And last question, would anyone care to share load data for such? Oh, really last question what should final size be (308, 309)?
Thank you all in advance.
