According to Wikipedia the original load of the .500 Nitro Express was a 570 grain bullet at 2150 fps, for the .500 Jeffery it was a 535 grain bullet at 2350 fps, and the .505 Gibbs pushed a 525 grain bullet at 2300 fps.
Using load data from Barnes which makes all these bullets, powder charges are .500 NE - 93.5 grs. (RL15), .500 Jeffery - 107 grs.(Varget), and .505 Gibbs - 138 grs. (RL22).
Case capacities are 138 grs., 158 grs., and 178 grs., respectively.
Using a standard weight of 11.5 pounds rifle, recoil figures are 75 lbs-ft., 88.5 lbs-ft., and 102 lbs-ft.
It's interesting to me how much effect on recoil the case capacity has as it necessitates a larger powder charge to get equivalent ballistics.
And yes, I'm bored from social isolation!
