Vectan Tubal(Tu) 2000 powder

Have ran across some Vectan Tu 2000 from a local seller. About 5-6 years old and from a 48 lb. keg. Not in original container. About 6 lbs. and can be had for maybe 10-11 bucks a lb. Vectan somewhat common in Europe, but the Tu2000 is no longer listed on Vectan's website. Current seller said he already has 6k rounds and doesn't need anymore. He used this with 55 grainers.
Not a whole bunch of info on the web, but from a couple of tables, looks to be mid point between fast and slow, in the same vein as N-130, N-133, IMR4198, H4198, H335, H322. Found an ADI(Australian Outback) site and has it in same category as H4198, IMR4198, and N-130. Also found a few recommendations for starters on some forums.
My 12FV seems to like heavier pills(68-69) on factory loads, which doesn't mean lighter(55) wouldn't work with hand loads. I was going to start some hand loads with the heavier pills.

Anybody have any experience with this? Too hot for 69ers? Too many unanswered questions that it would be best to pass? Seller said he had reload info, but didn't get into details.
