I picked up this mold at an auction recently. It's marked 287325. Now I know that the first three digits indicate the resize and not cast diameter, and the last three are the model number. I've looked in a lot of places and I cannot seem to find anything about this particular mold. The cast weight of the bullet is approximately 115gr and appears to be a gas check design. I erred on the title, it's not marked "Ideal", only Lyman. Anyone?
