Mold configuration for multiple different sizes?

[IMADMAN]

I'm looking to get a 4-6 cavity mold made with different bullet configurations. Caliber will be .30 but in different weights and designs. Is there a right way and a wrong way to set it up? Do I go smallest to biggest, biggest on the ends, smallest in the middle? Not sure if I have to worry about warpage?

I suspect 2 or 3 off the rack 2-3 cavity molds will be cheaper than the custom rig you suggest. Not sure your intentions, but most of us find we end up using one far more than any other. just my thought at 4:30 am

Unfortunately no. This mold will be made for airgun type slugs. Typically a new mold would run about $100 minimum.
