Until 1938, all M91 rifles and carbines were chambered for the rimless 6.5×52mm Modello 1895 cartridge, using a round-nose metal case bullet of 160 grains weight at approximately 2,000-2,400 ft/s muzzle velocity, depending upon barrel length. At least one small arms authority noted inconsistencies in powder types in arsenal-loaded 6.5×52mm military ammunition, often with different powder types and ammunition lots intermixed within a single clip of ammunition.
However, the Italian government was unable to successfully mass-produce the new arms in adequate quantities before the onset of war, and in 1940, all rifle and ammunition production reverted to 6.5 mm, but no 7.35 mm Mod. 38 rifles nor carbines were ever re-barreled to the old 6.5×52mm caliber. Some Italian troops serving on the Russian front were armed with 7.35 mm Mod. 1938 rifles, but exchanged them in 1942 for 6.5×52 mm arms. In 1941, the Italian military returned to a long-barrelled infantry rifle once again (slightly shorter than the original M91), the Carcano M91/41.
True sniper versions never existed, but in World War I a few rifles were fitted with telescopic lenses and issued for service use.
