The 307 Winchester was launched in 1982 for the Model 94AE (Angle Eject) lever action carbine. This was an ingenious design as fired cases were ejected from the right and it allowed the scope to be mounted directly above the action. Except for the rim, the dimensions of the 307 Winchester are the same as for the 308 Winchester and allows the M94 to be operated at higher pressures than the old 30-30 Winchester. It was one of three cartridges listed by Winchester for their Big-Bore rifle, the other being the 356 Win, a rimmed version of the 358 Winchester and the 375 Winchester, a more modern version of the old 38-55 Winchester.
