I am in the same boat. I moved here from Regina in Aug and before I left I noticed that there was not too much kicking around.
Here in Medicine Hat, all I have been able to find are CCI Maxi Mag and Federal Premium 30 grain loads which cost and arm and a leg at the local gunshop so I haven't bought them.
My favorite Winchester Super X 40 grain JHP arn't anywhere to be seen. That is because Winchester moved their ammo manufacturing plant and production was haulted for a bit. I hope WMR ammo becomes more plentiful soon.
