Bulk boxes (555 rounds) seem to be going for around $60 right now around here.
Sad as it is to say, if you sell it for around 0.10 to 0.12 / round, that appears to be roughly the going rate. If you push it up to 0.13 or higher, it may or may not sell, but you'll get a lot of griping about it.
Saw this at the Easter gun show for $120 - considering it's collector ammo, at the going rates for .22, it almost looked buyable and shootable.
I should have sucked it up and bought it. Probably the last time I'll ever see a brick of CIL Canuck still in the cellophane.
