About
What it is, and why it matters
The Hämmerli 202 is a Swiss .22 Long Rifle semi-automatic target pistol, part of the Hämmerli-Walther Olympia 200 series built in Lenzburg from 1955 under a Walther license derived from the pre-war Walther Model 1936 Olympia design. Effectively a Model 201 fitted with light-alloy construction and anatomical thumb-rest target grips, it retains the series' simple fixed-barrel blowback action, single-action trigger and finely adjustable target sights that made the Olympia line one of the dominant competition pistols of the 1950s.
After World War II, Hämmerli acquired the rights to Walther's medal-winning 1936 Olympia pistol and reintroduced it in 1952 as the Swiss-built 200 series - the same lineage that won five gold medals at the 1936 Berlin Olympics and later influenced the Smith & Wesson Model 41.
German-language references group the pistol as the 'Hämmerli-Walther 201/202', the light-alloy pair of the 200-series Olympia target pistols. Weight, magazine capacity and detailed dimensions for this specific variant are unconfirmed; the 190 mm barrel and .22 LR chambering follow the standard Olympia configuration.

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.
