The example I saw looked pretty kewl for a 255 grainer, combining elements of the intergalactically prevalent* Keith SWC by way of the NSSA Skirmisher ML projo, with the de rigeur RN/FP necessitated for most loading of .45 Colt
*If we ever get a working spacedrive, and go off to Rigel 7, or Reticulon Prime or Jaglan Beta, and visit a gun & reloading store there, odds are there will be Keith SWC's for sale in at least one caliber!

LOL!
Might want to ask Rocky or Terry Blauwkamp about the ideal profile for a projo for .45 Colt, truncated cone styles have had much popularity the last several years, but me being me if I were to have a TOTAL custom mould made, I'd want something as close as possible to the ideal bullet shape, a BT Spitzer
(Okay, we've got some constraints here with this being the 131 year old .45 Colt round and all....Ooooh! How about a "double ended" boat tail?? Severely bevelled base, front end would be of the Truncated Cone shape that's come to predominate for serious useage with those that actually load modern rounds. Ask The Rock if that would be worth bothering with, or just TMR's pain pills for the pulled tooth warping my tiny, rodent like brain)
Mold material--IF they can make it sturdy enough, go with aluminum. Rapidly warms up, if perchance your mold release compound thins out, lead alloys do NOT adhere. Not sure why anyone would want a brass/bronze alloy mould nowadays, if there's one thing tin-lead alloys like to stick to, it's cuprous alloys. VERY bad news if you do NOT de-flux your metal completely!
Since you're about to pull a Mad Reloader and delve into the wonderful world of Applied Science for Shootin' Fun, here's a suggestion for your Tropical grade all-natural bullet lube:
Time for TMR to also combine his love of Arcane Obscure Historical tidbits with his passion for "WEIRD SCIENCE" and shootin'!
The place was "Mother India" (check with UK Foxman & BBD, they would pronounce it EEEN-Jah!) the timeperiod a whisker before the Civil War.
The latest high-tech mil rifle was the 1853 Enfield, with disposeable paper cartridges that if used correctly gave one a cool .577 paper patched projo.
For use in blustery Merrie Old England, or the Cold White North of KANATA, lube was a mix of beef tallow & bacon drippins. A lot like the crumbly-sticky light gray stuff Hornady puts on their Great Plains projos.
NFG(!!) for places like the Great State of Texas, central/southern Arid-Zona and of course India {All hail the Gandhiji & the Netaji!
Jai Hind!}
(I am having WAAY too much fun writing this!

)
What the Brits came up with for their Hot Weather lead bullet lube involved...Carnauba wax!
Something to keep in mind.
Will post more later as I come up with more demented ideas.

LOL!
