It’s pretty well known that the 416 Rigby earned its reputation sending 410 grains downrange at 2,250-2,300 fps. The advertised velocity of 2,390 fps was in a 28 inch long proof barrel. Granted, cordite in the heat of Africa may have given the same (2,390 fps) from a 24-26 inch long barrel, but even today Kynoch loads the 416 Rigby to a mere 2,300 fps (410 grains, 26 inch barrel). Well, the 416 Ruger, even with a 20 inch barrel, will send 400 grains flying at an honest 2,250 fps. Yes, the pressure is higher but well within what is considered reasonable given modern powders, brass and all.
