About
What it is, and why it matters
The Hämmerli 205 is a Swiss .22 Long Rifle semi-automatic target pistol from the Hämmerli International 200 series, built in Lenzburg under a Walther license from the pre-war Walther Olympia design. Manufactured between 1956 and 1963, it is the top-of-the-line configuration of the Model 204 US-market pistol, carrying the same long fixed 7.5-inch barrel fitted with a muzzle brake and removable barrel weights and an adjustable micrometer rear sight, but distinguished by adjustable anatomical target grips for hand-fitted precision. The blowback-operated pistol feeds from a 10-round detachable magazine and was built for 25-metre standard-pistol competition.
Hämmerli built its International target pistols on the Walther Olympia design licensed from Carl Walther, pairing Swiss match-grade fit with a proven German blueprint that had dominated pre-war Olympic rapid-fire shooting; the Model 205 topped the series with hand-fitting adjustable grips.
Often marked 'Hämmerli-Walther'. Gun Digest lists the Model 205 as identical to the Model 204 but fitted with adjustable target grips; both were produced 1956-1963 as part of the International 200 series. Weight and overall length left null pending a documented figure for this specific model.

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.
