You'd have to make them. 180 grain might work as well.
I roll my own 7.62x54r 125's with reduced loading for plinking and pest control (close up coyotes and badgers, the like) and it works well, at least in my Mosins. It wouldn't be all that bad to use light bullets and turn that PSL into a lightweight subsonic straight-pull bolt action.
Again, what a sweet rifle/can combo! Hunting without all the noise
