Winchester White Box USA 25 ACP ammo remains the reference standard for shooters running legacy pocket pistols — Beretta 950, Colt 1908, Bauer .25 — where feeding geometry is tight and margin for error is zero. This 50-grain FMJ load clocks 760 feet per second from a 2-inch barrel, generating 64 foot-pounds of energy. The full metal jacket profile feeds from single-stack magazines without hang-ups, and the brass case extracts cleanly even in guns with fixed extractors. Intended use: range training, function testing, or carry backup when local regulation permits non-expanding projectiles.
Built for the Box
Winchester manufactures this load at their Alton, Illinois facility using domestically sourced components — cup-and-draw brass cases, non-corrosive Boxer primers, and ball powder metered to deliver consistent velocities across ambient temperatures. The 50-grain bullet is a swaged lead core wrapped in gilding metal jacket, crimped at the case mouth to prevent setback during chambering. Winchester has loaded .25 ACP since 1908 — the same year John Browning’s FN Model 1906 arrived stateside — and the engineering refinements accumulated over 118 years show in the load’s shot-to-shot uniformity.

Packaged in 50-round boxes, this load ships as DOT-regulated ORM-D freight. Brass cases reload without issue — anneal the necks after three firings to maintain tension, and use small pistol primers only. Find more 25 ACP ammo options for comparison or bulk orders.
