Edit: I just noticed I rand the #'s with the VLD Hunting... but QL data is the same for both the VLD and VLD hunt., so the data I provided is good to go.

I'm running 68gr of H1000 with 175 SMKs and getting a very easy 2920fps. You have the case capacity stick with H1000, for one it works well with large cases and long barrels. Two, it is very cool burning and will help with barrel life. For the brief period the F-Open team guys were shooting this cartridge I think they were getting around 3,150fps with the heavies.

As far as quickload you need to adjust the weighting factor for this case.
