Yes
100000000 meters
No, you cannot safely shoot a .45 caliber bullet from a .40 caliber handgun. The .40 caliber handgun is designed specifically for .40 S&W ammunition, which has a different casing size and bullet diameter compared to the .45 caliber. Attempting to use .45 caliber ammunition in a .40 caliber firearm could lead to dangerous malfunctions or serious injury. Always use the correct ammunition specified for your handgun.
That will depend on what caliber it is chambered for, the bullet used, the barrel used and the weather at the time. note: at one time the Magnum Research information state a 14" barrel 357 magnum gun could shoot up to 300 yards away (900 feet, or an eighth of a mile.)
