I ran into a problem Saturday night pouring. I was pouring football jigs in the Do It Molds with the 1/8, 1/4, 3/8, and 1/2 sizes. Everything was going fine until I got to the 1/2. I had been pouring them with the Mustad 3/0 32798, but I finally got some 4/0. The 1/2 oz can use the 4/0, that's what it says. The lead would not pour all the way for the 4/0, but works fine for the 3/0. If you were giving advice, would you all make the hook slot bigger or do I have another problem I'm not seeing. My pot is on the 8 slot when I pour, so my lead is hot enough. Thanks for any inight.
