FWIW: Brophy/"The Krag Rifle", (page 152) - "The 8mm Danish Cartridge was changed in 1908 to an improved pointed bullet and improved powder. The 'Safety Catch' was introduced in 1910. Brophy (page 154): "1. Rifle - There are four different types of barrel (A-D) ...." Per Brophy on barrel markings, (page 156):  OP's barrel is B-style barrel marked with - (script) "B" / three sided box indicates - "sharp edges of grooves" / 'crown' is proof mark. Follow madsenshooter's link to Gunboard's thread and discussion! I am sure there is some good data for Danish 8X58R, BUT, it is evident there is a lot of bad excessive pressure data on the internet!

No!
The krag will take "almost" anything you'll throw at it.
The problem is all the old black powder Remington Rolling Blocks that were converted to this caliber (Norway, Sweden, Denmark), they tend to self destruct when exposed to full house loads.

Nominal 8x58RD for Krags is 38,2kpsi and only 23,5kpsi for the old rollers.

Double Dutch to you but the Danish words say roughly: Middlepressure not to exceed 34,2kpsi and no MAX. pressure to exceed 41,2kpsi.
So if you squeeze the lemon then max. pressure is 41,2kpsi as that was deemed safe back then!
