They never made 335. In fact Hodgdon has never made any powder. They started by selling military surplus powder, and nowadays have their various powders produced by different companies.
The original powder was a pile of mil-surp stuff that was sorted according to burn rate. Some of it was BL-C, some of it was BL-C2 (Lot 2), and some was H335. There were probably other powders sorted from the same batch.
When the mil-surp stuff ran out in the early 1990's, Hodgdon contracted to have a similar powder produced. I acquired some of the new stuff but didn't know there was a difference. Had to reduce my long-standing .223 loads 2 grains.
