I have a M700 Remington "Classic" in 8x57JS, and I load the 180's to 2800, the 195 and 196 grain bullets to 2650 and the 200's to just a shade less than 2650.
With a modern, strong action and good bullets, the 8x57 will basically run with the 30-06 in hunting situations.
I have found Vihtavuori N150 and N550 to work very well in mine.
I have not tried it yet, but I think Reloder 17 might also be a winner.
FWIW, the brass with the largest internal capacity is the old "Dominion" brass, with Winchester next for capacity.
