yep, this is the best you find
we had it to, http://forums.nitroexpress.com/showflat.php?Cat=0&Number=239619&an=0&page=0#Post239619
the post war norma load make 579 m/sec with a 12,7 gramm/ 200 grains 8mm S roundnose. thats the maximum what could be safe in the rolling block or they made a higher load then. this was because the swedish hunting law asking for 2000 joule min. energie at 100 meter to hunt moose in this time and they want to use the rolling block because it was a common cheap farmer gun then.
you should be under this with your load.

Tried 14 grains trailboss with 196 grain full metal jacket projectile today averaged 1190 fps for 5 shots 14 grains was a 70 % load so will keep working up a grain at a time

With top-end loads, it should be producing in the neighbourhood of 28,000psi.

Likely H4895 or Varget. Hodgdon says the H4895 (AR2206H) can be loaded to 50% or 60% of it's max loading.
ADI / Hodgdon Propellants
ADI Powder Hodgdon / IMR naming
Trail Boss / Trail Boss
AR2207 / H4198
AR2219 / H322
BM2 / Benchmark
Bench Mark 8208 / 8208 XBR
AR2206H / H4895
AR2208 / Varget
AR2209 / H4350
AR2213H, AR2213SC / H4831 / H4831SC
AR2217 / H1000
AR2225 / Retumbo

Don't know if this helps, but here's reloading data for 8x58RD from the Norwegian Ladeboken. Only Vhitavouri powders though, but quick load might solve it.

Question, does it have a small diameter smokeless firing pin?
If so, that would keep me to light loads, something under 30,000psi. & closer to 25,000psi. Trail Boss will do that with a jacketed bullet and 100% load.
A .300 Win Mag loaded 100% Trail Boss with a 180gr. jacketed bullet made 28,000psi for Hodgdon.

the 1950s/60s Norma load for the swedish rolling block make 579 m/sec with the 200 grains softpoint
iirc, a E 100 of 200 Kgm was than minimum for hunting elk in sweden so Norma made the ammo it reach this benchmark. this was a careful load in my eyes the maximum in the old rolling block to be safe.

So - 1,900fps with a 200gr. bullet.
1,603.6fpe = 2,174.2 joules.

It probably would if I could read it
I think n135 is equivalent to w 748 so will try that in next couple of weeks
