Re: The light to medium calibers?

In reply to:
In Taylor's book of African Rifles and Cartridges he gives short shrift indeed to the 400-360's. He has high praises for other cartridges in the same class. What's the diff? He claims the 400-360 did not suit
Taylor did not have access to a chronograph so I guess he relied on quoted catologue ballistics.
If you were to use the ICI data for the 400-360 with 314 grain bullet it quotes 1900 fps and 2520 ft lbs energy.
The Nobel catalogue from the same era claims the 400-350 Rigby pushed a 310 grain bullet at 2150 fps for 3178 ft lbs energy!
Perhaps the big difference in claimed velocity and energy favouring the 400-350 Rigby could have influenced Taylors comments.
