7mm Mauser (7x57) Ammo 2026: Loads From Federal and Remington

By , EditorUpdated How we verifyEditorial standards

We checked 3 current 7mm Mauser (7x57) loads on Federal's and Remington's own product pages on November 5, 2026: 2 from Federal and 1 from Remington. 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 7mm Mauser (7x57) load sold.

Federal and Remington loads show the usage label each maker prints on its own page, copied as written. The Cartridge column shows the name the maker page uses.

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 140 gr to 175 gr. The lightest are Federal Power-Shok Rifle 140 gr (7B) and Remington Core-Lokt 140 gr (29031), and the heaviest is Federal Power-Shok Rifle 175 gr (7A). The fastest listed muzzle velocity is 2,660 fps, Federal Power-Shok Rifle 140 gr (7B) and Remington Core-Lokt 140 gr (29031), with no test barrel listed. The highest listed muzzle energy is 2,219 ft-lb, Federal Power-Shok Rifle 175 gr (7A), 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 3 loads, 3 list no test barrel. 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 7mm Mauser (7x57) is 24 in.

No barrel-length-velocity page exists yet for the 7mm Mauser (7x57), and we have not charted one. Our barrel length vs velocity data covers other cartridges, so do not read those numbers as 7mm Mauser (7x57) data.

7mm Mauser (7x57): what SAAMI lists

SAAMI lists the cartridge as "7MM MAUSER (7 X 57) [7MM (7 X 57)]" in ANSI/SAAMI Z299.4, its centerfire rifle standard (approved Feb. 10, 2025). The cartridge drawing was issued 05/29/1979 and revised 10/04/2022. SAAMI lists a maximum average pressure of 51,000 psi, measured by transducer (the table shows 510 in psi/100). SAAMI also lists a crusher maximum average pressure of 46,000 CUP (the table shows 460 in CUP/100). Cartridge overall length runs from 2.850 in minimum to 3.065 in maximum. Case length is 2.235 in (−.020). The drawing shows 4 grooves and a twist of 1 in 8.75 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 7mm Mauser MAP row is also on our SAAMI maximum average pressure table (Z299.4, 51,000 psi / 510 psi/100). Check any 7x57 load against your rifle’s markings and a gunsmith before shooting it in an older military rifle.

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 7mm Mauser (7x57), so SAAMI measures it on a 24 in barrel.
