I guess I'm confused. I thought today was your first loads you've ever done.
48 grains of Varget sounds like a pile. Maybe the barnes data is different, but it's a grain over max on the Hodgdon site, and more than 3 grains over the sierra data for a 150 grain bullet. Maybe I just need some sleep, but that looked like a light '06 charge, and when I think hunting, I think '06. =)
Edited to add - if he's not seeing anything grouping better than anything else, they all might be overpressure too. Again, don't know about Barnes bullets and I'm not researching anything right now. Have a good night.
