Does anyone have any idea where I could find ammo for a 9x57 (not 9.3)? I inherited this rifle and have a few rounds for it, but would like to get my hands on more. I know it can be hand loaded, but getting more brass would be nice too. The rounds I have are 250 grain soft round nose.

Buy some Norma or Sako 8X57 brass and neck up.
Not sure about shipping Canada to U.S. (it is impossible for us to import components from the U.S.), but 8MM brass is fairly easy to get up here.
 
I went thru this earlier this year.
You only have a couple of factory options: very old & expensive Kynoch or very new & expensive European sourced.

Reloading is a better option, but bullet availability runs from real common to you kinda have to fudge up your own.
You 100%, absolutely NEED to slug your bore, for one thing. 9mm is nominally .354", however your barrel may slug anywhere from that up to .358"!
If it's anything under .357, you're going to need a swaging dies, or set of them too take .358 bullets down in size. Reloading data is scarce & varies wildly! Brass can be formed from either 8x57 (cheap but doesn't last) or 9.3x57 (better life, but more spendy)

I have data that i'm happy to share, but with iron sights, you'll need to load to your sights, rather than a max velocity & my data is unlikely going to work for you, but it'll give you a start.
