It should....or I might be talking out my arse....give the bullet weight in grams in amongst the proof marks. Something like 12.7 g or somesuch...which will be 196 grain. Or maybe some lighter weight expressed as xx.x g in the proof marks.
First, look on the barrel for the date of manufacture.
Early 8x57I and 8x57IR were regulated for 14.7 gram or 227-grain bullets, the original weight.
Until 1914, many rifles did not have marks for the regulation bullet weight, and up to 1920, many were regulated for 227-gr or heavier, like 13.0 grains.
Most drillings after that will be regulated for 12.7 grams, or 196 grains, with a particular measure of flake powder, not muzzle velocity or chamber pressure. To further complicate matters, the chemistry of smokeless powders was progressing rapidly, and the proofs changing to keep up.
But to simplify matters, a drilling or double rifle, or 1888 rifle will shoot to the sights in good groups with a variety of bullet weights, from 150 grains to 240 grains.
I have dismantled Wermacht and Turkish 8x57IS rounds of varying bullet weights to measure the powder and type, and reuse the powder with the same bullets in my rifles. If you know your rifle's proof date and the powder and bullet marks, you can probably find surplus military ammunition and duplicate it the regulation load.
8x57JR 196-gr ammunition should be about 2,325 fps from a 27-inch barrel ( like the 1888 bolt action), and a bit less for a 24-inch barrel. By comparison, the same bullet from am 8x57IS bolt action would be about 2,525 FPS from a 23.6 ( 600mm barrel).
So look at the Norma and VV and other load data books for 8x57IS loads in this range and find a powder you have or can obtain, and work up towards these velocities.
The Lee data which comes with their dies is very useful for figuring loads of the right pressures.
