You seem to have done a good job of knowing what you want. Here is a link to Ranch Dog's 432-265 bullet for sale.

If you like that bullet (and I am confident that you will) then you can shop around for one of those molds. If you can not find the mold, you can go to one of the mold makers like Mountain Molds or Accurate molds or a similar mold maker and they can make a copy of that mold for you.
This bullet with my wheel weight alloy, weighs about 275 grains. You say you like speed? My load for the RD432-265 has higher muzzle velocity than the 265gr Hornady Superperformance factory load in my 22" barrel. 2315 fps avg. for RD432-265 and 2296 fps avg. for the Superperformance factory load.
