This will depend to some degree on the barrel length. A 4 inch .38 Special revolver has an effective range of about 50-60 yards.
Depends to some degree on the barrel length. A 4 inch revolver has a maximum range of about 1000 meters- however, the maximum EFFECTIVE range is about 50-60 meters. That is the range where a shooter can reliably hit the target.

3 miles
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.

Depending on who makes it, they can range from 25-5000 USD.
The strongest ammo available for .38 (and for most any other caliber) is plus-P-plus. However, .38 special is not particularly effective against bears.
A .38 Special bullet can travel approximately 1,000 to 1,500 yards (about 0.57 to 0.85 miles) when fired from a handgun, depending on the specific load, barrel length, and environmental conditions. However, its effective range for accuracy is much shorter, typically around 50 to 100 yards. Beyond this range, the bullet's velocity decreases significantly, and it becomes less reliable for hitting a target.
