Seafire, neither Bl-2, 748 or H-335 are FLAKE powders, they're ball powders. If your H-335 can had FLAKE powder in it I can see why you blew up two action as the only FLAKE powders I know of are much faster burning shotgun or handgun powders.

H-335 powder has been one of my best powders in the 6x45mm with 55gr bullets. I also use it in my 223, 22-204, and 25-204

Siera, Hogdon, Hornady and Lee reloading manuals have data for the 6x45mm. Hogdon has an online sight with data for the 6x45mm and they have a very inexpensive magezine style manual with data for the 6x45mm and anumber of other wildcats.
