I have a similar load for my 7mm08: 48 grains of Ramshot Hunter with a 2.85" COAL and a 160 Partition for 2811 fps from my 25" gun.
Do you have adequate neck tension with your OAL out so far? That seems marginal from the picture. Nice gun.
I don't mean to imply that 7x57 isn't awesome, just that 7mm08 is great in it's own right.
*Load is a maximum load for my rifle and could blow yours up etc. Do not use etc, you could die etc....
