It was the same as Win 785 and both are extinct as far as I know. I used a couple of 8lb kegs of 785 back in the day and I liked it for 85gr bullets in the 243 and 6mm. Look in an older reloading manual for load info.
I used H450 a lot back in the mid to late '70's in one of the 243's I had. It metered really well and shot great with the Sierra 85gr HPBT bullets. Then it disappeared from the shelves one day and I've been using WW760 and others in the 243 every since for hunting. WD
