I agree with mule deer, I wouldn’t put much weight into the flattened primers.
To me the 62.8 load looks promising both velocity wise and grouping especially if you think you may have not shot your best group.
I’m not extremely familiar with the Hodgdon powders as I usually use IMR’s and reloader. Another option that will be similar to the 4350’s is RL-17. Although I couldn’t duplicate the accuracy of the IMR4350 a lot of people really like it for wsm calibers.
On another note, once you starting trying the AB’s and E-tips take a look at the Nosler book. They have load data on a bunch of different powders.
