.25 Auto (.25 ACP) Ammo Guide

By Cole Harlan, EditorUpdated Nov 5, 2026How we verifyEditorial standards

We load-checked five factory .25 Auto loads on Federal's, Hornady's and Remington's own product pages on November 5, 2026: two from Federal, two from Hornady and one from Remington. .25 ACP, .25 Auto and SAAMI's "25 Automatic" are the same cartridge. Muzzle velocity and energy below are copied from those maker pages. We don't list prices or use retailer ballistics. Test barrels differ: Federal AE25AP and both Hornady loads list 2 in, while Federal PD25P1 and Remington 23716 print no test barrel. SAAMI's V&P test barrel is 2.000 in (50.80 mm).

A dash means the maker page prints no test barrel (not yet verified). Barrels differ across these loads, so they are not ranked against each other.

SAAMI pressure

SAAMI lists a maximum average pressure (MAP) of 25,000 psi for 25 Automatic, measured by transducer (printed as 250 psi/100), in ANSI/SAAMI Z299.3-2022 (SAAMI PDF). The test barrel is 2.000 in (50.80 mm), drawn as a V&P Test Barrel, with a twist of 16.00 in L.H. Transducer MPLM is 25,800 psi and MPSM is 27,000 psi. SAAMI also prints a crusher MAP of 18,000 psi. See every cartridge on the SAAMI MAP pressure chart.

Defense and training lines, by maker name

We group loads only by the maker's own line names. American Eagle and UMC Handgun are range and training lines. Personal Defense Punch and Critical Defense are defense-named lines, and Hornady's 35 gr XTP is listed under its bullet name as printed. We do not rank these loads or recommend one over another.

Test barrels differ

Federal AE25AP and both Hornady loads list a 2 in test barrel, Federal PD25P1 and Remington 23716 print none, and SAAMI's V&P test barrel is 2.000 in. We show maker numbers as printed and do not reconcile or rank them across barrels. We did not read SAAMI reference velocities for this cartridge.

Not yet verified: Winchester, Speer, CCI and SIG were not fetched. Checked November 5, 2026.

See the SAAMI MAP chart, the .32 Auto ammo guide, the .380 ACP ammo guide, the 9mm ammo guide and all ammo releases.
