Norma Reloading Information from 1963

Many of the loads listed on this one-page technical information flyer produced by Norma for the 7 x 61 Sharpe and Hart use IMR 4350. Just click on the images to see the full page at a readable and printable size.

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.
