It won’t be a surprise that an 18″ carbine delivers substantially higher velocities than a 4″ revolver firing the same cartridge.
It weighs six pounds and holds 5+1 rounds. 30-30: an early-1990s Winchester Model 1894 ‘Trapper’ with a 16.5″ barrel. 357 Magnum pistol: a 1980s Smith & Wesson Model 686 with a 4″ barrel.
It has an 18″ round barrel, weighs a little over six pounds, and holds 9+1 rounds. 357 Magnum carbine: a new-production Marlin 1894C. 30-30’s biggest drawback: it’s a shorter-range cartridge, due to the flat-point bullets that must be used in a tubular magazine. In modern military terms it would be considered an ‘intermediate-caliber’ round, packing about the same punch as the 7.62×39. It may be pretty weak sauce compared to more modern, high-velocity rounds, but it still gets the job done for most game at reasonable ranges. Hell, in Utah they use it to execute two-legged predators. Since 1895 it may have killed more deer and elk (and cougars and coyotes…) than all other calibers combined. 30-30 was once the standard North American big-game hunting cartridge.
