i struggled to get a good fillout on some of the bullets i cast. they have a wrinkle in the head. i wouldn't call it a "crack" just a wrinkle. They are nice and mirror finish though. I turned up the heat a bit and got an amazing fill out of the mold but... they are "frosted".
Does a frosted bullet make a diffrence in saftey while shooting them? Because.. if i can get good fill out but have frosted bullets instead of mirror tip finish ones... fine. i'll take it.
Also; i'll take tips on how to get a good fillout WITHOUT having frosted tips. I've tried smoking the molds again, lower heat, higher heat, fluxing the lead (seems to have cloged my bottom pour pot though).
