I certainly do. As long as you are ordering a standard bullet form, I'll cut almost any diameter or weight you want, and can often make the next larger size gas check work great, if there is no check for the oddball caliber. This by making a special check shank to center the large check while sizing them on.
It may take a bit longer than for one of the cataloged bullets for me to make your mold, but not much. I haven't been able to get the dreamed of stock of molds to ship on receipt of order and am making most molds as they come in anyhow.
