.32 Auto (.32 ACP) Ammo Guide

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

We load-checked six factory .32 Auto loads on Federal's, Remington's and Hornady's own product pages on November 5, 2026: three from Federal, one from Remington and two from Hornady. .32 ACP, .32 Auto and SAAMI's "32 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 AE32AP and P32HS1 and Hornady 90062 list 4 in, Hornady Critical Defense 90063 lists 2 in, and Federal P32HSD1 and Remington 23704 print no test barrel. SAAMI's V&P test barrel is 4.000 in (101.60 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 20,500 psi for 32 Automatic, measured by transducer (printed as 205 psi/100), in ANSI/SAAMI Z299.3-2022 (SAAMI PDF). The test barrel is 4.000 in (101.60 mm), drawn as a V&P Test Barrel, with a twist of 16.00 in L.H. Transducer MPLM is 21,100 psi and MPSM is 22,100 psi. SAAMI also prints a crusher MAP of 15,000 psi. See every cartridge on the SAAMI MAP pressure chart.

Defense, training and hunting lines, by maker name

We group loads only by the maker's own line names. Personal Defense Hydra-Shok, Personal Defense Hydra-Shok Deep and Critical Defense are defense-oriented lines. American Eagle and UMC Handgun are range and training lines. Hornady Custom (XTP) is a hunting and target line. We do not rank these loads or recommend one over another.

Test barrels differ

Federal and Hornady list 4 in on three loads, Hornady lists 2 in on Critical Defense, two loads print no barrel, and SAAMI's V&P test barrel is 4.000 in. Maker muzzle velocity and energy are not SAAMI reference velocities (SAAMI Test Bbl references: 71 gr 900 fps; 80 gr 1,140 fps). The SAAMI reference velocity for 65 gr is not yet verified. We show maker numbers as printed and do not reconcile or rank them across barrels.

Not yet verified: Winchester. Its .32 Auto product pages we found (X32SCP and others) show no ballistics data. Speer and CCI were not checked. The SAAMI 65 gr reference velocity could not be read reliably from the PDF text. Checked November 5, 2026.

See the SAAMI MAP chart, the .32 H&R Magnum ammo guide, the .327 Federal Magnum ammo guide, the .25 Auto ammo guide, the .38 Special ammo guide, the .357 Magnum ammo guide and all ammo releases.
