Does anyone know of a casting mold to work with this round?

Slug your bore to find out what diameter you actually need. One of the following is likely to fit the bill....

Currently available molds that are appropriate:
Lee C312-185-1R - 185 gr RN/GC

Lyman 314299 - 200 gr RN/GC

Saeco 305 - 180 gr FN/GC

There are others that may work, but there's no guarantee that the mold would drop a bullet with a large enough diameter. And... that Lyman mold needs a fairly hard alloy, or it will drop undersize bullets.

Beyond those, you'd have to look through the catalogs of the other mold manufacturers (there are dozens), or try to find a used mold with an old design that you prefer.

A start:
www.magmaengineering.com/bullet-molds/
www.accuratemolds.com/ (these are all custom designs)
www.hochmoulds.com/
www.mountainmolds.com/ (design your own)
www.neihandtools.com/
www.oldwestbulletmoulds.com/
www.noebulletmolds.com/ (unless it's in stock, expect a 2 year wait)
www.ballisti-cast.com/Bullet%20Designs.htm
www.mp-molds.com/
http://www.ranchdogoutdoors.com/inde...x&cPath=1_5_16 (two custom designs in Lee molds)
www.three-peaks.net/bullet_molds.htm

And, a Google search will yield even more.
