Admittedly I lived just 12 minutes from the range back then but, I set up at 100, fired 5, cold bore, into one hole (all touching), packed up and left. There is virtually no way that day could get any better, for me at least, lol.
As far as the bad day goes, been there, done that. Looking back at those I figured out it was all me; something else going on in life preventing me from being totally focused on the job at hand. Now when I hear words like "if you leave now honey you can be back by 2:00 pm", nope, not gonna do that. Tomorrow will be here soon enough.
Not sure if this would work for you but it's worth considering. A group of avid shooters at the range where I'm a member pooled their cash and bought an AMP induction annealing machine, its kept it in a locker at the range. They allocate a certain amount of range time to annealing. Works for them and no one person had to cough up the full freight.
I don't really know anything about this area of QL. The filter criteria is outlined at the top of the output file, nothing there looks out of sorts. I do notice once I select this output QL becomes locked up, I have to end it and start over if I want to go back to a different output. Probably a program bug.
I don't know what it is with Varget and 308, they just seem well matched. I took direction from guys at my old range, they swore by Varget with 308, never heard a single person say it didn't work for them in that caliber.
I've also had excellent results using Varget for 6.5 Grendel and 35 Remington.
I developed the load for the Steyr before I had a chronograph or QuickLoad, it was developed the old-fashioned way.
I ran the powders for you assuming 43.0 gr powder except for RL16 where I went to 46.0 to get it more in useful range. I couldn't find the XBR 8208 in the QL database. Went with a classic bullet, SMK 168 BTHP.
Hope these help, let me know if you want some more specific drill downs for certain powders.
I use Varget for my Steyr Scout that has a 16" barrel, it works real well with 168 gr bullets. Can't say I've really done any sophisticated load development for the rifle, 41.8 gr Varget comes to mind.
Anyway, I can help with QL, let me know as much as you can so we don't have to guess.
Here's a screen shot of some of the input details we can specify with QL.
