I don't do split shots myself but with any mold, it's gotta be hot. Even though you made a few pours, its prolly still not hot enough believe it or not. Good hot lead, with hot enough molds, will pour easy and the weights will come out smooth, no wrinkles.
I keep my mold on a oven burner a lot. Some folks add some kind of wax or something too,,,maybe someone will chime in on that. I've learned that hot lead, a hot mold, and swift pouring does the job. Any pause in between pours will cool stuff off fast. I've poured them so hot that my handles are about smoking, LOL.
Try it out and let us know..we'll help ya figure it out.
