I don't know the exact barrel diameter of a 32 acp and a 7.65mm (in comparison) but I wonder if the area where the rounds go is sleeved, like the chamber adapter that changed a 30-06 to 308 by fire forming / fitting with either epoxy or by tightness?

Ed

looked it up

32 acp https://en.wikipedia.org/wiki/.32_ACP
Bullet diameter .3125 in (7.94 mm)

7.65mm
Bullet diameter 7.85 mm (0.309 in)

so, it sounds to me that it could be 'bored' out a bit and just the bore sleeved?

Other thoughts?

Rich?
