.450 Bushmaster Ammo 2026: Hunting and Range Loads From the Makers

By , EditorUpdated How we verifyEditorial standards

We checked 10 current .450 Bushmaster loads on Federal's, Remington's and Hornady's own product pages on November 4, 2026: 3 from Federal, 3 from Remington and 4 from Hornady. The bullet weights, velocities, energy figures, test barrels and statuses below are copied from the maker pages. We don't use retailer prices or third-party ballistics. This is a comparison of popular loads from 3 makers, not every .450 Bushmaster load sold.

Grouping follows the usage label Federal and Remington print on their own pages. Hornady is listed in its own table, because Hornady prints no usage label. The Cartridge column shows the name the maker page uses.

Hunting loads

These are the loads Federal and Remington label Big Game on their own pages. Figures are copied from each maker page.

Hornady loads

Hornady's pages show no usage label and no stock status on our capture, so these loads are listed by product line, such as American Whitetail, American Whitetail Tipped, BLACK and Sub-X Subsonic. Velocity and energy are the muzzle figures from each page's ballistics table.

Velocity and energy are the muzzle figures in each maker's ballistics table. Test barrel is the length the maker lists. "Box" is the round count per box. Status is the maker's own wording on its product page, and it changes daily. All pages checked November 4, 2026.

Which bullet weight? What the makers' numbers show

Loads in our table run from 245 gr to 395 gr. The lightest is Hornady American Whitetail (82242) and the heaviest is Hornady Sub-X Subsonic (82247). The fastest listed muzzle velocity is 2,200 fps, Federal Fusion Rifle 260 gr (F450BMFS1), with no test barrel listed. The highest listed muzzle energy is 2,794 ft-lb, Federal Fusion Rifle 260 gr (F450BMFS1), with no test barrel listed. Because test barrels differ or are not listed, compare across makers with care.

The makers label loads for game or for target use. They don't tell you one weight is right for a species. The right choice depends on bullet construction, range and your state's rules. Check your state hunting rules and your state wildlife agency before you buy.

Barrel length matters: the test barrels

Muzzle velocity depends on barrel length, so compare loads tested on the same barrel. Of the 10 loads, 6 list no test barrel, 4 list 20 in. The loads with no test barrel are from Federal and Remington. A rifle with a shorter barrel than the maker's test barrel will likely give lower velocities than the box. SAAMI's test barrel for the .450 Bushmaster is 24 in.

No barrel-length-velocity page exists yet for the .450 Bushmaster, and we have not charted one. Our barrel length vs velocity data covers other cartridges. The closest we have are 7.62x39 barrel length data and 300 Blackout barrel length data, for the 7.62x39 or the 300 Blackout (other AR-pattern rifle cartridges; we have no barrel page for any .45 caliber rifle cartridge), so do not read those numbers as .450 Bushmaster data.

.450 Bushmaster: what SAAMI lists

SAAMI lists the cartridge as "450 BUSHMASTER [450 BM]" in ANSI/SAAMI Z299.4, its centerfire rifle standard (approved Feb. 10, 2025). The cartridge drawing was issued 02/01/2008 and revised 08/23/2022. SAAMI lists a maximum average pressure of 38,500 psi, measured by transducer (the table shows 385 in psi/100). Crusher pressures are not established. Cartridge overall length runs from 2.000 in minimum to 2.260 in maximum. Case length is 1.700 in (−.010), and bullet diameter is .4525 in (−.0030). Bore is .442 in and groove is .450 in, with 6 grooves and a twist of 1 in 24.00 in, right-hand (marked optional). SAAMI reference velocities are Not yet verified, because the PDF text does not clearly pair each bullet weight with its velocity. Read the standard at the SAAMI Z299.4 PDF.

SAAMI says all standard rifle test barrels are 24 in long and that exterior ballistic data for centerfire rifle cartridges is based on that length. Its listed exceptions (7.62x39, 277 Sig Fury, 30 Carbine, 300 AAC Blackout, 300 HAM'R, 350 Legend, 350 Remington Magnum, 360 Buckhammer, 400 Legend and 44 Remington Magnum) do not include the .450 Bushmaster.
