To some extent, this will depend on the weapon that fires the cartridge. Assuming that your question relates to the .38 Special cartridge, when fired from a 4 inch barreled revolver, the bullet would have a maximum range of about 1800 meters. This would be when the barrel was elevated at about a 45 degree angle. The effective range (usable) would be less than 100 meters. If fired from a rifle (yes, there are rifles that will fire a .38 Special) the range would be greater than if fired from a revolver. If fired from a 2 inch barreled (snub nosed) revolver, the max range would be less.
