I dunno, but I been loading up to max trying to get the highest velocity in my 1919a4 barreled sks.  No idea what the pressures will be for surplus ammo.

Barnaul I'm not saying that info isn't available but I've been unable to find it. Maybe an email to Wolf?

45K psi at the max I imagine. Probably around 38k realistically. But I'll be honest, I have no idea what m43 is. I'm just talking generic x39 loads.

The SAAMI Maximum Average Pressure (MAP) for this cartridge is 45,000 psi (310.26 MPa) piezo pressure.

Somewhere I remember a pressure for single shot style weapons, which was just slightly higher.  47000-48000 somewhere in this range.
