Can you get hodgdon's leverevolution over there? or perhaps CFE223? These 2 powders have the longest "legs" for 6Arc heavier bullets.
Also according to several users (I myself use the GRT tool, which is free), QL is difficult to set up for accurate modeling of these shorter, fatter cartridges, like Grendel and 6 Arc.
I find I have to first calibrate the model by trying to duplicate mfr load data, then re-calibrate again when I get some chrono data on my own barrel.
If you do not have a chrony, I would heartily recommend to get one. Personally I like the magnetospeed the best as it is easy to set up and portable, and doesn't require a cold firing line so you can do setup 15-20 ft downrange. Cheaper than the lab-radar outfits. But any chrony you can get will be a help.
