375 H&H Magnum Ammo 2026: Big Game Loads From the Makers

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

We checked 10 current .375 H&H Magnum loads on Federal's, Remington's and Hornady's own product pages on November 5, 2026: 5 from Federal, 1 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 .375 H&H Magnum 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 DGS, DGX Bonded, Outfitter and Superformance. 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 DGS	375 H&H	82322	300 gr DGS®	2,530 fps	4,263 ft-lb	24 in	20	Not listed on maker page
Hornady DGX Bonded	375 H&H Magnum	82334	300 gr DGX® Bonded	2,530 fps	4,263 ft-lb	24 in	20	Not listed on maker page
Hornady Outfitter	375 H&H Mag	823314	250 gr CX® Outfitter®	2,700 fps	4,047 ft-lb	24 in	20	Not listed on maker page
Hornady Superformance	375 H&H	8508	270 gr SP-RP Superformance®	2,800 fps	4,699 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 250 gr to 300 gr. The lightest is Hornady Outfitter 250 gr (823314), and the heaviest are 6 loads, including Federal Power-Shok Rifle 300 gr (375B) and Federal Safari Swift A-Frame 300 gr (P375SA). The fastest listed muzzle velocity is 2,800 fps, Hornady Superformance 270 gr (8508), tested on a 24 in barrel. The highest listed muzzle energy is 4,699 ft-lb, Hornady Superformance 270 gr (8508), tested on a 24 in barrel. 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 24 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 .375 H&H Magnum is 24 in.

No barrel-length-velocity page exists yet for the .375 H&H Magnum, and we have not charted one. Our barrel length vs velocity data covers other cartridges, so do not read those numbers as .375 H&H Magnum data.

.375 H&H Magnum: what SAAMI lists

SAAMI lists the cartridge as "375 HOLLAND & HOLLAND MAGNUM [375 H&H MAG]" in ANSI/SAAMI Z299.4, its centerfire rifle standard (approved Feb. 10, 2025). The cartridge drawing was issued 04/21/1980 and revised 08/03/2022. SAAMI lists a maximum average pressure of 62,000 psi, measured by transducer (the table shows 620 in psi/100). SAAMI also lists a crusher maximum average pressure of 53,000 CUP (the table shows 530 in CUP/100). Cartridge overall length runs from 3.475 in minimum to 3.600 in maximum. Case length is 2.850 in (−.020), and bullet diameter is .376 in (−.003). Bore is .366 in and groove is .376 in, with 6 grooves and a twist of 1 in 12.00 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. The .375 Holland & Holland Magnum MAP row is also on our SAAMI maximum average pressure table (Z299.4, 62,000 psi / 620 psi/100).

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 .375 H&H Magnum, so SAAMI measures it on a 24 in barrel.

Not yet verified

These makers and loads are not in the tables.

Winchester: the only Winchester .375 item we found in its sitemap (X375W) is the .375 Winchester, a different cartridge, so it is not here. We found no Winchester .375 H&H Magnum item.
Federal custom shop: item FCS375 is a build-your-own page that prints no velocity, so it is left out.
Other .375 cartridges: the .375 Ruger and other .375-caliber cartridges are different cartridges and are not in this guide.
Remington: the one load in the table (29097) is the only 375 H&H Magnum item among the 201 rifle pages in Remington's product sitemap that we opened on Nov. 5, so a load missing from that sitemap would not be here.
SIG Sauer, Nosler, Berger, Barnes, Browning, Norma, Sellier & Bellot and others: not checked this round, so none are in the tables.
Federal: Federal's loads were found through its sitemap, so a load missing from its sitemap would not be here.
Hornady: loads come from Hornady's product sitemap, so a load missing from that sitemap 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.
