Birdhunter50,
I now have my reference material at hand, so will try to answer your additional questions you posed:

The breach pressures indicated below are all in British LONG TONS. One Long Ton = 2240 pounds.

.577 3" double rifle data that may interest you:

Bell's Greener rifle, made in 1900. Pictured and written about in DGJ, it was .577 Light Nitro, original factory load was 80 grains cordite, 650 grain bullet. Overall rifle weight 11 lbs, 3 oz.

A British hammer .577 3" had engraved on rifle 75 gr. cordite, 650 gr. bullet, 1850 fps. Rifle overall weight 12.5 lbs. John Taylor said this was load (transitional load) developed to replace black powder.

On flats of Jeffery .577 3 1/4" 177 gr. (black) 650 gr. bullet. Rifle weighed 11 lbs, 5 oz.

Loads for .577 black and light nitro:
