When we look at the sub-44Mag rounds there is a plethora of popular options in the "smaller" calibers. Working backwards: 44Mag, 41Mag, 45 Colt, 10mm, 44 Spcl, 45 ACP, 45 Gap, 40S&W, 357Mag, 357Sig, 9mm, 38Super, 38Spcl, 380Auto, 327Fed, 32Mag, 32acp, 25acp, 22Mag, 22LR. In short, we go from muzzle energies of 70 ft-lbs (25acp) to 900 ft-lbs (44Mag) in 19 steps averaging 44 ft-lbs each. That step size drops to 35 ft-lbs when you consider the slightly odd calibers: 357 SuperMag, 45 Super, 38 Super and a couple others.
But when we go up from the 44Mag the common options are few: 454Casull, 50AE, 460S&W Mag and 500S&W Mag. The energy increases from 900 to 2,500 ft-lbs, or steps of 400 ft-lbs each!! Even if you throw in the rare cartridges like 460 Rowland, 480 Ruger, 50 Wyoming Express, 375 & 445 SuperMags the "steps" are still a whooping 180 ft-lbs each.
Given this disparity, why aren't more large cartridges popular? Why do market entries like the 460 Rowland, the 480 Ruger and the Dan Wesson SuperMags, which helped to spread the gap, have such a hard time becoming successful? Going from a 44Mag to a 454Casull doubles the already large energy, wouldn't a few more options between those be useful?
