Early Selfloader Mania: Italy's First Semiauto Battle Rifle, the Armaguerra Model 1939, with Forgotten Weapons
By this point, it’s impossible to hide my affinity for early selfloading rifles, and today we have another great video from Forgotten Weapons on an early Italian model that made it all the way to adoption. Though the program was cancelled before it could be produced, the Armaguerra Model 1939 rifle is still an important piece of Italian firearms history. You can learn more about it in Ian’s video embedded below:
A History of Military Rifle Calibers: The .30 Caliber Era, 1904-1954
A trend towards ever more powerful and longer-ranged ammunition was cut short by the realities of the First World War: Technologies not previously invented or accounted for, such as the man-reaping machine gun and the portable infantry mortar, made the existing infantry tactics of long-range volley fire not just obsolete, but quaint. Further, new essential small arms projectile designs like tracers, armor piercing bullets, and exploding observation rounds demanded more space in the projectile envelope, putting the previously cutting-edge small-caliber 6.5mm rounds at a disadvantage. The advantages of these small-caliber rounds were virtually negated, too, by the advent in 1905 of the German S-Patrone, a flat-based, pointed projectile that was vastly more efficient in supersonic flight than previous round-nosed designs. Although French engineers preceded this design with the superior (and top secret) Balle D round, it was the German bullet that became the pattern for military rifle projectiles worldwide.
