About
What it is, and why it matters
The Mosin-Nagant M/28 is a bolt-action rifle developed by the Finnish Civil Guard (Suojeluskunta) and assembled at the SAKO factory as a marksman's battle rifle chambered in 7.62x54mmR. Built on the Russian Mosin-Nagant M1891 receiver, it pairs a new heavy free-floated barrel, a two-piece birch stock, and an improved windage-adjustable front sight to deliver far greater accuracy than the original Russian pattern. Roughly 33,000 were produced between 1928 and 1932, and the type is famously associated with Finnish sniper Simo Hayha.
The M/28 is reputed to be the rifle wielded by Simo Hayha, the Finnish marksman nicknamed the 'White Death,' who is credited with hundreds of kills using iron sights during the Winter War.
Finnish 7.62x53R service ammunition is dimensionally interchangeable with 7.62x54mmR. The M/28 used SIG, Tikkakoski, and a small number of SAKO barrels, all assembled at the SAKO works.

Trajectory
What the round does downrange
Solved from the muzzle figures and the bullet. The dashed rule is the effective range on the record, and the crosses are the steps the solver returned.
No load solved for this record yetThe flight path is computed from a cartridge and a bullet. This record has no ammunition filed against its chambering, so there is nothing to solve.
