.300 WSM Ammo 2026: Hunting Loads From the Makers

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

We checked 17 current .300 WSM loads on Federal's, Remington's and Hornady's own product pages on November 5, 2026: 11 from Federal, 3 from Remington and 3 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 .300 WSM 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.

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, Outfitter and Precision Hunter. 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 American Whitetail	300 WSM	82204	165 gr InterLock® American Whitetail®	3,130 fps	3,589 ft-lb	24 in	20	Not listed on maker page
Hornady Outfitter	300 WSM	822034	180 gr CX® Outfitter®	2,900 fps	3,361 ft-lb	24 in	20	Not listed on maker page
Hornady Precision Hunter	300 WSM	82208	200 gr ELD-X® Precision Hunter®	2,820 fps	3,531 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 150 gr to 200 gr. The lightest is 2 loads at 150 gr, including Remington Core-Lokt Tipped (29043) and the heaviest is 3 loads at 200 gr, including Federal ELD-X (P300WSMELDX1). The fastest listed muzzle velocity is 3,340 fps, Remington Core-Lokt Tipped 150 gr (29043), with no test barrel listed. The highest listed muzzle energy is 3,715 ft-lb, Remington Core-Lokt Tipped 150 gr (29043), 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 17 loads, 14 list no test barrel, 3 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 .300 WSM is 24 in.

No barrel-length-velocity page exists yet for the .300 WSM, and we have not charted one. Our barrel length vs velocity data covers other cartridges. The closest we have are .300 Win Mag barrel length data, for the .300 Winchester Magnum (the same .308 bullet diameter in a longer belted magnum case, not the same cartridge), so do not read those numbers as .300 WSM data.

.300 WSM: what SAAMI lists

SAAMI lists the cartridge as "300 WINCHESTER SHORT MAGNUM [300 WSM]" in ANSI/SAAMI Z299.4, its centerfire rifle standard (approved Feb. 10, 2025). The cartridge drawing was issued 06/13/2001 and revised 06/01/2022. SAAMI lists a maximum average pressure of 65,000 psi, measured by transducer (the table shows 650 in psi/100). Crusher pressures are not established. Cartridge overall length runs from 2.560 in minimum to 2.860 in maximum. Case length is 2.100 in (−.020), and bullet diameter is .309 in (−.003). Bore is .300 in and groove is .308 in, with 4 grooves and a twist of 1 in 10.00 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 .300 WSM MAP row is also on our SAAMI maximum average pressure table (Z299.4, 65,000 psi / 650 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 .300 WSM, so SAAMI measures it on a 24 in barrel.

Not yet verified

These makers and loads are not in the tables.

Winchester: we opened 10 Winchester .300 WSM item pages on Nov. 5 (X300WSM, X300WSM1, X300SCLF, X300SCLF2, X300SDS, X300SDS2, SBST300S, SBST300SA, S300SLR and S300SBC) and every one said "There is no ballistics data available at this time," so we have no Winchester figures to copy.
Federal custom shop: items FCS300WSMA and FCS300WSMLRX1 are custom-shop pages and are left out. FCS300WSMA prints no velocity. FCS300WSMLRX1 (200 gr Barnes LRX) prints a muzzle velocity but no energy figure or ballistics table, so we did not use it. Federal's unprimed brass is a component, not a loaded round.
Remington: the three loads in the table (29043, 29345 and 29489) are the only .300 WSM items we found on Remington's rifle pages, so a load missing from those pages would not be here.
SIG Sauer: the maker's site returned an access error (403) to our automated check, and we did not verify its product pages.
Nosler, Berger, Barnes, Browning, Norma and others: not checked this round, so none are in the tables.
Federal: Federal's loads were found through its sitemap and the Caliber field on each rifle product page, so a load missing from those 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.

Frequently asked questions

What is the SAAMI maximum pressure for .300 WSM?

SAAMI lists a maximum average pressure of 65,000 psi for .300 WSM, measured by transducer, in ANSI/SAAMI Z299.4 (the table shows 650 in psi/100).

What grain is .300 WSM ammo?

In our tables the bullets run from 150 gr to 200 gr. Check your firearm maker's manual for what your rifle is set up to shoot.

How fast is .300 WSM ammo?

In our tables, listed muzzle velocities run from 2,810 fps to 3,340 fps, and muzzle energies from 3,246 ft-lb to 3,715 ft-lb. Test barrels vary, and some maker pages list none. See the test barrel section of this guide.

What does test barrel mean?

It is the barrel length the maker used to measure the listed velocity. A shorter barrel will likely give lower velocities than the box.

Do you list prices or stock for .300 WSM ammo?

No. We link only to maker pages. Where a maker page shows a status, such as "Available" or "Currently Unavailable," we copy it as of Nov. 5, 2026. Hornady's pages show none.
