Sorry but I just ran across this post. Here's one I made out of aluminum that enables you to get the exact length you need without cutting. Weights are consistent. This is a tailweight mold. The slugs are actually from a similar bellyweight mold without the core rods so you get the idea. Capping the cavities with a relatively small feed hole results in a very small sprue that is easily trimmed with a pair of nippers. I pour with a small bottom pour furnace. I prefer to press my slugs into my plugs and file off the excess which is minimal. That way I don't have to mess with wood fillers. I get a consistent weight on each batch of plugs this way. You could probably use a blank Do-it mold and cap it like I did with my homemade.
