"Prior to 1945 factory ammunition loaded with 3,2 gram BP (~49.4 grains) and a 14,7 gram (227 grain) lead projectile was available with a muzzle velocity of around 1450 fps.
Subsequent factory ammunition was available with 12,5 gram (193 grain) and 13 gram (200 grain) copper jacketed bullets. The former as FP the latter as SP with about 2010 fps and the 200 grain with 2250 fps all loaded with R5 powder. The 200 grain loading was supposed to be a +P as we would call it today and only for suitable rifles it was known as the “Dornheim-Patrone” (Dornheim cartridge). The intent was a usage for bigger game."

Will also add Norma ammo is i think the 193gr @ 2000ish fps load, and that if i could have a drilling, it would be a nitro proofed 16x16x9.3x72, rather than the x74. Why? Because i dont think the x74 is needed for most of the use a drilling would see.
