    Will a .38 special round expand larger and more reliably out of a 4 inch barrel then a .357 magnum out of a 3 inch barrel?

    81,

    Obviously it would depend upon the ammunition you are shooting. But I do know that the 357 Mag with 3 in. Barrel produces around 1200 Ft.Lbs of energy at the muzzle and the 38 Special from a 4" Barrel produces around 960-1000 Ft. Lbs. of energy at the muzzle. So I guess we could assume that the 357 even from the 3" barrel is a more powerful cartridge than that of the 38 Special form a 4" barrel. Different rounds perform differently according to velocity. But generally speaking yes the 357 with also higher velocity and energy would have more expansion.
