Sorry if I posted this in the wrong section I'm brand new and this is my first post. Can someone please let me know why when pouring these hooks I'm getting pinholes. Clean lead warm molds using a Lee Pro 4-20 pot and SMB-4-MTD mold. My first attempt was with football swing jigs ran 100 without any issue. Thanks in advance for any ideas..... This and baits what an addiction !!
