You're in Regina, I assume you've tried TNT gunworks, so start working your way outwards. How about trying Jo Brook firearms in Brandon? Or Wolverine in Virden (their site doesn't list loading stuff, and I never saw any when I was there, but who knows). After them, perhaps try Frontier Firearms. Or try your luck with the Wholesale sports or Cabela's websites. Primers are out there, stores are finally starting to be able to hold on to stocks of them.
