The 105×617mm (4.1 inch) also known as 105 × 617 R is a common, NATO-standard, tank gun cartridge used in 105mm guns such as those derived from the Royal Ordnance L7. The 105 × 617 R cartridge was originally developed from the 84 mm (3.3 in) calibre Ordnance QF 20-pounder 84 × 618R cartridge as part of the development of the L7 105 mm rifled gun.
