! EN ! ! ! ! 20 AMMUNITION WARNING: Beretta assumes no liability for physical injury or property damage resulting from the use of defective, improper, hand-loaded, reloaded or remanufactured ammunition. Serious damage or injury, even death, may be caused from the use of ammunition that is not suitable, loaded with force, or loaded with obstructions in the barrel. The Beretta A400 Xplor semi-automatic shotgun has different cartridge chambers, depending on the version. The shotgun does not require adjustments or interventions to shoot from 70 mm (2 3/4 in) /24 g (7/8 oz), to 76 mm (3 in) /57 g (2 oz) cartridges. The "UNICO" version without any adjustments or interventions can shoot from 70 mm (2 3/4 in) /24 g (7/8 oz) to the powerful Supermagnum 89 mm (3 in.) /64 g (2 1/4 oz) loads. Beretta recommends: To immediately obtain superior firearm performance and optimum cartdridge versatility from your A400 Xplor, fire some medium power cartridges first (32g / 1 1/8 oz). CAUTION: The Beretta semi-automatic A400 Xplor has an Optima-Bore® HP barrel and Optimachoke® HP choke tubes that make it possible to fire High Performance steel shot ammunition. Follow the instructions for use of choke tubes appropriate for the use of steel shot, as set out in the "Steel shot" section. You will find the markings for the gauge and chamber length for your shotgun on the side of the barrel (Fig. 20). Every A400 Xplor has been tested with special proof test ammunition at 1320 bar with high performance steel shot. These tests guarantee the ability to shoot either ordinary or HP steel shot (usually higher than 3.5 mm of diameter) which cause higher pressure in the barrel. CAUTION: Never use cartridges that do not correspond to the indicators on the barrel. CAUTION: Only use cartridges with a length equal to or less than the chamber length indicated on the barrel. CAUTION: To avoid using improper ammunition, always check the characteristics stamped on the cartridge box and on the cartridge. Be sure to use the right cartridge gauge and length for your firearm. STEEL SHOT All Beretta barrels, as well as the "SP" (Steel Proof) Beretta choke tubes, are designed for use with factory steel shot cartridges loaded to international standard specifications. When steel shot cartridges are fired, the best results are obtained by using open chokes (C0000/CL, 0000/IC, 000/M). Full choke constrictions (0/F, 00/M) when using steel shot, do not increase pattern density
