Winchester Model 1907
Produced by Winchester Repeating Arms Company
The Winchester Model 1907 is a blowback-operated, semi-automatic rifle produced by the Winchester Repeating Arms Company beginning in 1907 with production ending in 1957. It fired a cartridge of intermediate power, cycled through a semi-automatic operating mechanism, fed from a 5, 10, or 15 round detachable box magazine located immediately forward of the trigger guard. In size and handling, it is much like an M1 carbine, though the 1907 is heavier and fires a much harder hitting round. The only cartridge offered by Winchester as a factory chambering in the Model 1907 was the .351SL centerfire. The energy of this cartridge at the muzzle approximates the original loading of the .30-30 or the modern .35 Remington at approximately 75–100 yd (69–91 m).
