can i fire blanks in a real gun
Blank (cartridge) For movie use, specially designed blank-firing firearms are often used, which increases the margin of safety as they cannot be loaded with live ammunition. 5-in-1 blanks are specifically made for theatrical use and are commonly used in real firearms for dramatic effect. 5-in-1 blanks can function in a variety of different calibres, hence the name.
Shotgun Slug rounds are rounds that fire a single solid slug. They are used for hunting large game, and in certain military and law enforcement applications. Modern slugs are moderately accurate, especially when fired from special rifled slug barrels. They are often used in "shotgun-only" hunting zones near inhabited areas, where rifles are prohibited due to their greater range.
