About
What it is, and why it matters
The CS/LR3 (military designation QBU-141) is a Chinese bolt-action precision rifle designed and manufactured by Norinco. Chambered for the dedicated DBU-141 5.8x42mm match-grade cartridge, it is intended as a designated marksman / police precision rifle for ranges out to roughly 600 m. The free-floating heavy barrel, adjustable polymer chassis-style stock, and bipod-equipped fore-end give the rifle around 1 MOA accuracy with issued ammunition.
The CS/LR3 ships with its own purpose-designed 5.8x42mm DBU-141 match cartridge - Norinco's answer to the West's habit of pairing rifles with off-the-shelf 7.62 NATO match loads. The rifle and round were essentially co-developed.
The CS/LR3 was designed alongside the matched DBU-141 cartridge - making it one of the few sniper rifles built specifically around a precision-tuned variant of an existing service round. Despite a similar designator, it is unrelated to the larger 7.62x51mm CS/LR4.

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.
