Lately I've been buying through Boca Bearings, but I vaguely remember once buying one of those Wheels Mfg bottles. I don't remember if it was from Jenson, but I remember them being listed as Grade 300, but when they arrived it said Grade 25 on the bottle anyway. I just assumed that Wheels didn't bother stocking grade 300 anymore as the price difference is probably smaller than the cost of inventory overhead.
