Roger at Shooter's Choice (home-based business in Arrowood, approximately 40 km north of Vulcan) has Federal 525 bulk .22LR for $24 per box, or $230 per case of 10 (GST included). I think those prices are correct.......check his website:

While you're there, you may find other things to buy, too!!
You will be hard-pressed to find a nicer gentleman!
Good luck
