The Mosin–Nagant is a five-shot, bolt-action, internal magazine–fed military rifle. Known officially as the 3-line rifle M1891[9] and informally in Russia and the former Soviet Union as Mosin's rifle (Russian: винтовка Мосина, ISO 9: vintovka Mosina), it is primarily found chambered for its original 7.62×54mmR cartridge.
Developed from 1882 to 1891, it was used by the armed forces of the Russian Empire, the Soviet Union and various other states. It is one of the most mass-produced military bolt-action rifles in history, with over 37 million units produced since 1891. In spite of its age, it has been used in various conflicts around the world up to the present day.
Most Finnish Rifles were assembled by SAKO, Tikkakoski Oy, or VKT (Valtion Kivääritehdas, State Rifle Factory, after the wars part of Valtion Metallitehtaat (Valmet), State Metalworks). The Finnish cartridge 7.62×53mmR is a slightly modified variation of the Russian 7.62×54mmR, and is considered interchangeable with 54R. However, the older version of the Finnish military cartridge was loaded with the S-type bullet that had nominal diameter of .308. In 1936 the Finnish Army fielded a new standard service cartridge intended for both machine guns and rifles. This new cartridge was loaded with a new bullet designed in 1934–the D-166, which had a nominal diameter of .310. The new service rifle m/39 was designed from the start around the D-166 thus it had nominal barrel diameter of .310.
Handloaded cartridges for Finnish rifles should however use a 0.308 inches (7.8 mm) bullet for use with other Finnish Mosin–Nagant variants instead of the 0.310 inches (7.9 mm) one which gives best results in M/39, Soviet and most of other Mosin–Nagant rifles.
M/28–30: An upgraded version of the M/28. The most noticeable modification is the new rear sight design. The same sight was used in following M/39 rifle only exception being "1.5" marking for closest range to clarify it for users. According to micrometer measurements and comparison to modern Lapua D46/47 bullet radar trajectory data, markings are matched to Finnish Lapua D46/D46 bullet surprisingly accurately through whole adjustment range between 150 m and 2000 m.
The trigger was also improved by adding coil spring to minimize very long pre-travel. Following M/39 does not have this improvement. The magazine was also modified to prevent jamming. Magazines were stamped with "HV" (häiriövapaa = Jam Free) letters in right side of rifle. Later M/39 uses identical design, but without "HV" -stamp. M/28–30 also have metal sleeve in fore-end of handguard, to reduce barrel harmonics change and to make barrel-stock contact more constant between shots and/or during environmental changes such as moisture and temperature. Later M/39 does not have this upgrade.
In addition to its military usage, approximately 440 M/28–30 rifles were manufactured by SAKO for use in the 1937 World Shooting Championships in Helsinki.
M/28–30 model, serial number 60974, was also used by Simo Häyhä, a well-known Finnish sniper. M/28–30 was used as Civil Guards competition rifle before World War II, as was the case with Simo Häyhä's personal rifle. Therefore, rifles were built very well, with highest grade barrels available and carefully matched headspace. Häyhä's rifle was still at PKarPr (Northern Karelia Brigade) museum in 2002, then moved to an unknown place by the Finnish Army.[41]
I have set them to a 1:35/1:72 ratio for easy printing, and the size comes from the data provided by the encyclopedia. You can adjust its size to any place by yourself.
Note: If using the model for 3D printing, model repairs may be needed.
