Cabelas does (remington and federal). So does Wholesalesports (at least remington is in stock in Winnipeg). If you're shooting a ruger #1 or lever gun, there are other (more expensive) options available.
Wholesalesports used to carry a 405Gr hard cast FP made by cactus plains which sold for about $60/250 (for the bullet). These are my 'plinker' rounds (46Gr 4198 CCI BR primers, remington brass). They do about 1800fps out of a 18.5" bbl and group about 1" at 100 yards for me. I can send you a few if you like. The experience will probably be enough to get you into reloading.
I reload my own 99% since I find the factory ammunition to have horrible accuracy.
If you don't want to reload your own, I'll happily buy your once fired brass to help subsidize your factory ammo ;-)
