It is my understanding that the .32-20 and the .32 WSL (and the .300 Whisper for that matter) all have approx. the same case capacity. I know the .300 Whisper operates at 50+ kpsi so that data is out, but the .32 WSL was a 35-40 kpsi cartridge. If the .30 Carbine has similar capacity, that might work too but I've never heard of a heavy bullet .30 Carbine load. What I'm getting at is if anyone has .32 WSL load data they are willing to share. I'm looking at creating 140-180gr .32-20 loads (not subsonic) for a single-shot rifle project. Pressure would be 35-40 kpsi. The closest I've come is 8.2gr of 2400 with a 165gr LFP for a Contender Carbine but no pressure was listed nor who made the bullet. Paco Kelly lists a 150gr load, but the bullet he used isn't available. Thanks in advance.
