Its definitely an experimental load. 32 projectiles are around 60-75gr, while 7.62x39 are around 125-150. Im certain it wouldnt cycle, and the ballistic performance would be abysmal. I once tried something similar with 100gr 30-06 loads using 30 luger projectiles.
I still have the stuff for those loads lying around. Mostly as a joke for people expecting a big kick, or for newer shooters I dont want to get kicked too badly.
I have loaded 32 ACP bullets in 7.7 Japanese, 303 Brit, and 7.62x54R. Here is somethings I have learned:
Gallery loads (using a really fast powder to produce a low recoil round) are a great way to introduce new shooters. The rounds are cheaper, the recoil lighter, and they are reasonably accurate to 25 yards.
When pushed to full pressures don't expect accuracy. The rifling on rifles is not designed around such a light and short bullet, so it can end up either being un balanced or even skipping rifling in places. Depending on the gun it can be really bad grouping or "what is this grouping thing you are talking about?"
Also when testing velocity be extra careful if you have an optical chorograph. You might end up with an expected new ventilation hole in it.

Send it, it will be fine and I’d love to see it.

Why would that possibly work? 7.62 is .30 cal. You gonna send a .32 cal projectile through a .30 cal barrel?

7.62x39 projectile is roughly .311 in diameter while 32acp is .312. It might work.

I'll take the L on that one but I still wouldn't risk it.

It’s similar to the compatibility of .38 special and .357 mag, the listed name for a certain cartridge is very frequently not the actual size.

Often diameter of lands vs grooves.

Send it.
Post the ft/s and bullet weight.
45mag@reddit (OP)
Pretty much the same as a regular 308

Uh....maybe?
This'll depend greatly on which 7.62 and .32 you're trying to use.
American/NATO 7.62 is .308"
Soviet 7.62 is .311"
Most .32 pistol calibers are 0.312 only one I thing you'd somewhat reliably find being different is .32 Webely (0.317)
And center fire rifle .32 calibers vary are usually about 0.321"
