I used GameKings in the same 30-06 load for decades. I was using Hodgdon H450 powder and when Hodgdon quit selling it I never found a powder that shot as well with the GameKings.
I ended up having to push them hard to get any accuracy, and then on a close range front quartering shot, one blew up in the shoulder and failed to penetrate to the vitals. When you shoot a deer in the shoulder from 25 yards with a 30-06, you don't expect it to just run off! That shook my confidence in them and I started hunting with a 25-06 and a 45-70 for several years until I could find a good load again for the 30-06. Accubonds were the ticket.
