need to brake the system and regulate it when
firing powerful ammunition etc.) and those of the
gas operated type (need to clean gas outlets, loss
of power due to acceleration of the shot charge
and adverse effect on the longitudinal conform-
ation of the wad and possible malfunctions
under adverse climatic conditions), producing a
modern, highly reliable gun.
The new semi-automatic shotguns work with a
vast range of shells. The inertia system requires,
in any case, shells that generate enough kinetic energy (recoil) to fully cycle the action.
The vast experience of our ballistic laboratory
and extensive field testing have allowed us to
establish exactly the right parameters needed to
ensure the correct functioning of your shotgun.
In particular, we have determined 200 kgm as
the minimum kinetic energy required from a 12
gauge cartridge (measured at 1 m from the
muzzle of a manometric barrel). WARNING: at the minimum kinetic energy stat-
ed above, correct functioning is only guaranteed
for a shotgun with a MAXIMUM total weight of
3.150 kg.
