It's interesting to me that they list the approximate pressures of the different loads. From other literature I got with the gun, one of the complaints about some of the early (i.e. late 1940's) writing about the cartridge was that most early published performance information came from very high pressure loads in a gun with a 30" barrel. While some of the pressures Norma publishes here climb close to 58,000, there are a lot of 3,000 plus FPS loads here with pressures right around 50,000.
