Good afternoon, as the post suggests this is all new to me. Casting has peaked my interests and I've slowly began to acquire the equipment to start. My goal is to begin with .223, 9mm, and 300 BO. I have about of 100 pounds of w/w ingots waiting to be shaped into flying goodness. A couple of questions I have are related to these rounds being powder coated. I understand working loads up but where do you guys start? The cast handbook the 223 55g. is around the 16ish grain yet I see video after video of guys loading in the 20's. That would be a tremendous amount of time to progress from such a low starting point. Secondly, when it comes to the velocities of powder coated they seem to be higher than tumble lubed cast. Is this the factor allowing the hotter rounds? Thanks for any help or direction.
