I recently bought some Techrim/Fedarm brass 8x57. From what I understand its German surplus 197g Projectile loaded with Gew.bl.p.436 or Nz.Gew.Bl.P 2-2-0-45? maybe they’re the same thing?. I was measuring the powder loads in these rounds which seemed to be off 2-4 grains. I was wondering what the typical load should be for these and what is considered the upper limit? It seems most people use IMR4064 for a commercial powder and 44 is considered a upper limit? I’m worried about overpressure. Maybe it’s a non issue.
