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 fi rearm performance and
optimum cartdridge versatility from your A400 Xplor, fi re some medium power
cartridges fi rst (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 fi re 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 fi nd 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 fi rearm.
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 specifi cations. When steel shot cartridges are fi red, 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
