Slugs can be made very easily by getting a suitably thick piece if wood, 1/4" for this purpose and drilling holes through it of the required diameter over groove. Clamp it to a flat surface and pour your melted soft lead in to the holes, let cool and push out with a nail, trim off any sprue and voila a slug.
For throat imapct slugs use a suitably thicker wood say 1", 1 1/4".
A more refined amd permanent version is to get a thicker piece of wood or metal, drill a pilot hole through for each diameter slug you think you will need big enough for a nail to go through. Then open these holes up to your required diameters and depths. Then pour, cool and push out. Trim sprues and away you go. Don't choose too thick a piece of wood or the pilot hole sprue will be to long and make pushing out the slug a struggle.
Obviously for impact slugs they will need to be under bore diameter, bore slugs over groove diameter.
Good idea. Thanks.

So easy and so obvious once you know, I have some lead and wood, the Viking has a ladle in the kitchen, job done :)
Yet another Master Class tip, it is good we have a few oldies on the forum.
