==History== After gaining its independence in 1917 and after the Finnish Civil War of 1918, large numbers of Model 1891 Mosin–Nagant rifles were in the hands of the Finnish military. As the old barrels were worn out, they were replaced by new 7.83 mm (.308 in) barrels and the leftover 7.62×54mmR cartridges being in short supply, a domestic product was needed. This gave birth to the 7.62×53mmR.
