Thanks John,
The density of Big Game should definitely make it easier to get enough powder under a 250gr NAB or 286gr NP in a 9.3x62 than with Varget for top velocities.
Xterminator looks like a good way to get enough powder under a 110gr or 115gr for a good whitetail load in 6.8 SPC. I just hope its temperature stable enough to be consistent in all conditions.
