Abstract

The hunting gun has a bolt assembly comprising two parts, namely a locking head and a floating element with a spring interposed between the two parts. The locking head comprises essentially one or more projections adapted to engage corresponding recesses in the cylindrical internal surface of the breech and a surface inclined with respect to the breech axis and adapted to engage a mating surface of the floating element. Upon firing the gun recoils but the floating element, being free in the gun, tends to keep its position and keeps the locking head with its projections in engagement with the grooves in the breech. Thus, there is a delay in the opening of the cartridge chamber, which prevents unlocking of the gun in the charge explosion step, i.e. at the time of greatest gas expansion. When the recoil force has decreased to a predetermined extent the spring pushes back the floating element which slides with its inclined surface on the mating surface of the locking head permitting the latter to lower and disengage its projections from the recesses in the breech so that the locking head can also recoil under the action of the residual force of the spring.
