[QUOTE="dreamer94, post: 340708, member: 6449"]I don't think it's an oddball question. The new H.E. Harris holders have inserts made of plastic foam.

The question I have is, how are you going to cut the holes in the cardboard? I looked into doing this and I can't find any affordable tool that can cut perfect circles. All I could find was professional die-cutting equipment that can cost tens of thousands of dollars, not counting the cost of custom making the dies.
