Greyfox and I both have similar results regarding the speed. 54 grains H4831sc gave me 2900 FPS. so I bet he is dead on. 50 gr H4350 was 2850. I looked at my notes and I could only seat .015 as max due to my chamber having a long throat. I don't feel comfortable having a low bullet depth in the neck of the case and they seemed very fragile.
I burned 4x what you did getting a better load set up, although I had decent sub MOA accuracy out of the rounds. I always liked the smallest jump I could get but both my Savages fell in love with .100 out. I did notice when I do bullet seating depth checks that I need to push the bullet firmly into the lands, set my gauge, and then push the bullet back out with the cleaning rod. For some reason there is slight hang up spot with a little extra force it goes in a bit further.
Guess it is time to find the pressure node and work back down. Good job again. Happy for you.
