can't find any molds or any makers of molds that list one.

Tom at http://accuratemolds.com/ has cataloged designs that are close, but tell him what you want and he will make it exactly. His prices are competitive with pre-made molds for the big companies.

Take a look at 31-072W and 31-077C on the first page of the catalog. He can modify either one to your specs, or make an entirely new design. These two are nominally 31 caliber, but will probably cast a little over size.

Lyman made the 311252 which is shown as a 75 gr bullet.

Check M&P moulds

Lyman #311252 casts a 71gr bullet out of Pure Linotype.
Which comes out at 98 bullets to the pound.

The 311252 is the classic Lyman mold for 32 ACP. Also works in 32 S&W. It has been in production for a long time.

Paul your correct. But try to find one priced reasonably.

Tom's process won't produce a true round nose, so you will end up with a .18 meplat in .32 ACP similar to this one:

Though heavier than 71gn when modified(milled shorter)the Lee 311-100-2R makes a very accurate and reliable feeding boolit. Mine drop at 80gn but I've read of others that cut their molds a bit shorter and they drop in the 73-74gn range.

I’ve been using the Lyman .311252 in various .32’s since the 90’s.
Mine casts to 78gr. With the same powder charges as 71gr jacketed bullets, it gives equal or higher velocities at similar pressures. I use 2.0grn of Bullseye. Sized .311”

Recent testing in media and more sophisticated analysis of wound ballistics reveals what was understood in the early 20th century. These little guns as far more effective than has been credited when loaded to original specifications. IE: European CIP standards.
Fiocchi factory 73gr RN runs 875fps from my KelTec P32, and 1,000fps from my Beretta M81.
I’ve seen Remington 71gr RN run 690fps from the KelTec! Winchester 60gr Silvertip is 850fps from KelTec. 60gr Fiocchi is 975fps and hits 1,100 from the Berreta.

My .32acp’s also work with the Lee 90gr TLSWC and 93gr RN at .311” 1.6gr of Bullseye runs both at ~700fps.

GONRA's also a "311252 IDEAL" mould fan. Loaded 100's .32ACP over the decades.....
Sized/Lubed boollts weighed 70-80 grains with my scrap alloys....

I'm casting that mould and it comes in right about there. Very good for my Baby Vaq's.

Out of curiosity, why is 71 grain needed?

I believe that the OP wants to match the payload and velocity of factory ammo.

However, the lighter 71-grain bullet was a post-WW2 change when the lead core material was changed from pure elemental lead to recycled salvaged lead scrap containing about 3% antimony. Earlier .32 ACP and 7.65mm Browning loads, both US and European, were loaded with heavier 74-77-grain bullets.

Interesting. I just thought, like other cartridges, a cast bullet was longer (thus heavier ) to more closely match jacketed lengths for proper feeding.
