.458 Lott Ammo 2026: Dangerous Game Loads From Federal and Hornady

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

We checked 5 current .458 Lott loads on Federal's and Hornady's own product pages on November 5, 2026: 3 from Federal and 2 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 2 makers, not every .458 Lott load sold.

Federal and Remington loads show the usage label each maker prints on its own page, copied as written. Hornady is listed in its own table, because Hornady prints no usage label. The Cartridge column shows the name the maker page uses.

Federal loads

Figures are copied from each maker page. The usage label is the maker’s own wording.

Load	Cartridge	Item #	Bullet	Muzzle velocity	Muzzle energy	Test barrel	Box	Maker usage label	Maker status (Nov. 5)
Federal Safari Trophy Bonded Bear Claw	458 Lott	P458LT1	500 gr Trophy Bonded Bear Claw	2,300 fps	5,873 ft-lb	Not listed on maker page	20	Big Game, Safari	Currently Unavailable

Federal Safari Woodleigh Hydro Solid	458 Lott	P458LWH	500 gr Woodleigh Hydro Solid	2,250 fps	5,620 ft-lb	Not listed on maker page	20	Big Game, Safari	Check With Your Local Ammo

Hornady loads

Hornady's pages show no usage label and no stock status on our capture, so these loads are listed by product line, the Dangerous Game Series. Velocity and energy are the muzzle figures from each page's ballistics table, and the test barrel is the one the table names.

Load	Cartridge	Item #	Bullet	Muzzle velocity	Muzzle energy	Test barrel	Box	Maker status (Nov. 5)
Hornady Dangerous Game Series	458 Lott	82614	500 gr DGX® Bonded	2,300 fps	5,873 ft-lb	24 in	20	Not listed on maker page
Hornady Dangerous Game Series	458 Lott	8262	500 gr DGS®	2,300 fps	5,873 ft-lb	24 in	20	Not listed on maker page

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 5, 2026.

Which bullet weight? What the makers' numbers show

Loads in our tables run from 500 gr to 500 gr. The lightest are 5 loads, including Federal Safari Trophy Bonded Bear Claw 500 gr (P458LT1) and Federal Safari Trophy Bonded Sledgehammer Solid 500 gr (P458LT2), and the heaviest are 5 loads, including Federal Safari Trophy Bonded Bear Claw 500 gr (P458LT1) and Federal Safari Trophy Bonded Sledgehammer Solid 500 gr (P458LT2). The fastest listed muzzle velocity is 2,300 fps, 4 loads, including Federal Safari Trophy Bonded Bear Claw 500 gr (P458LT1) and Federal Safari Trophy Bonded Sledgehammer Solid 500 gr (P458LT2), on differing test barrels. The highest listed muzzle energy is 5,873 ft-lb, 4 loads, including Federal Safari Trophy Bonded Bear Claw 500 gr (P458LT1) and Federal Safari Trophy Bonded Sledgehammer Solid 500 gr (P458LT2), on differing test barrels. 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 5 loads, 3 list no test barrel, 2 list 24 in. The loads with no test barrel are from Federal. 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 .458 Lott is 24 in.

No barrel-length-velocity page exists yet for the .458 Lott, and we have not charted one. Our barrel length vs velocity data covers other cartridges, so do not read those numbers as .458 Lott data.

.458 Lott: what SAAMI lists

SAAMI lists the cartridge as "458 LOTT [458 LOTT]" in ANSI/SAAMI Z299.4, its centerfire rifle standard (approved Feb. 10, 2025). The cartridge drawing was issued 06/04/1998 and revised 01/21/2024. SAAMI lists a maximum average pressure of 62,500 psi, measured by transducer (the table shows 625 in psi/100). SAAMI prints crusher pressures for this cartridge as Not Established, so we quote only the transducer figure. Cartridge overall length runs from 3.400 in minimum to 3.600 in maximum. Case length is 2.800 in (−.020). The drawing shows 6 grooves and a twist of 1 in 10.00 in, right-hand (marked optional). Bullet, bore and groove diameters are Not yet verified, because the PDF text does not pair each figure with its label clearly. 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. The .458 Lott MAP row is also on our SAAMI maximum average pressure table (Z299.4, 62,500 psi / 625 psi/100). SAAMI lists the .458 Winchester Magnum on its own drawing; it is a different cartridge and is not in this guide.

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 .458 Lott, so SAAMI measures it on a 24 in barrel.

Not yet verified

These makers and loads are not in the tables.

Item codes versus cartridges: Federal's Safari items with codes P458LT1, P458LT2 and P458LWH carry the Caliber field “458 Lott” and are in the table. The items P458T1, P458T2, P458T3 and P458WH carry “458 Win Magnum,” so they are left out. We went by each page’s Caliber field, not the item code.
Hornady's two pages print the same table: the 500 gr DGS page (item 8262) and the DGX Bonded page (item 82614) show identical ballistics, 2,300 fps and 5,873 ft-lb at the muzzle, with the same figures out to 300 yards. We copied both as printed and could not tell why they match, so check the box or Hornady before relying on either.
Hornady: Hornady’s .458 Win Mag DGS Superformance page is a different cartridge and is not in the table.
Federal Custom Shop: Federal’s custom .458 Lott page (build-your-own) was not opened, so none are in the table.
Remington: none of the 201 rifle pages in Remington's product sitemap that we opened on Nov. 5 and checked by Caliber field is a .458 Lott load.
Winchester: not checked this round, so none are in the table.
SIG Sauer, Nosler, Berger, Barnes, Browning, Norma, Sellier & Bellot and others: not checked this round, so none are in the tables.
Hornady: loads come from the Hornady product pages we saved, so a load missing from them would not be in the table.
Test barrels and stock status: Federal and Remington pages list no test barrel, and Hornady's pages list no stock status.
SAAMI: reference velocities for this cartridge are Not yet verified (PDF layout is ambiguous), so none are copied.
