.460 S&W Magnum Ammo Guide

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

We load-checked five factory .460 S&W Magnum loads on Federal's and Hornady's own product pages on November 5, 2026: three from Federal and two from Hornady. Muzzle velocity and energy below are copied from those maker pages. We don't list prices or use retailer ballistics. Test barrels differ: Federal prints 8.4-V on two loads and 8.4V on the third, Hornady 9152 lists 8.375 in, Hornady 9153 lists 8 in, and SAAMI's solid test barrel is 10.000 in (254.00 mm). We do not rank loads across makers.

Barrels differ across these loads, so they are not ranked against each other. Federal prints its test barrel as 8.4-V (P460XB1 prints 8.4V).

SAAMI pressure

SAAMI lists a maximum average pressure (MAP) of 65,000 psi for 460 S&W Magnum, measured by transducer (printed as 650 psi/100), in ANSI/SAAMI Z299.3-2022 (SAAMI PDF). The test barrel is 10.000 in (254.00 mm) SOLID, printed as one-piece/unvented. SAAMI also prints a vented overall length of 10.746 in and a vented segment of 8.375 in, with a twist of 20.00 in R.H. and 5 grooves. Crusher is Not Established. Transducer MPLM is 67,100 psi and MPSM is 70,200 psi. See every cartridge on the SAAMI MAP pressure chart.

Hunting lines, by maker name

We group loads only by the maker's own line names. Swift A-Frame, Fusion, Barnes Expander, Custom (FTX) and Handgun Hunter (MonoFlex) are the product names these makers use for these loads. We do not rank them or recommend one over another.

Test barrels differ

Federal prints 8.4-V on two loads and 8.4V on one, Hornady lists 8.375 in on 9152 and 8 in on 9153, and SAAMI's solid test barrel is 10.000 in. Maker muzzle velocity and energy are not SAAMI reference velocities. We show maker numbers as printed and do not reconcile or rank them across makers or barrels.

Not yet verified: Remington: no .460 listing found on our check. Hornady 91558 is left out because Hornady publishes no ballistics for it. Winchester, Speer, CCI and SIG were not fetched. SAAMI's vented-barrel velocities are Not Established, and we do not list SAAMI reference velocities. Checked November 5, 2026.

See the SAAMI MAP chart, the .454 Casull ammo guide, the .500 S&W Magnum ammo guide, the .44 Magnum ammo guide and all ammo releases.
