7mm-08 Rem vs .308 Win: Maker-Page Loads and SAAMI Specs Side by Side

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

This page puts 7mm-08 Rem and .308 Win side by side using only our own ammo guides, 7mm-08 Rem ammo (19 loads) and .308 Win ammo (86 loads), plus the cartridge specs SAAMI publishes in ANSI/SAAMI Z299.4, its centerfire rifle standard. The guides copy bullet weights, velocities, energies and test barrels from maker product pages (checked Nov. 4–5, 2026). We don’t rate or rank cartridges, and we don’t subtract one maker’s velocity from another’s, because their test barrels differ.

How to read this page: every number is copied from a maker page or from SAAMI, and a test barrel length sits next to every velocity (or says the maker lists none). A dash (—) means the maker has no load in our tables for that cartridge. Fire only the cartridge your firearm’s maker says it is chambered for.

SAAMI specs side by side

These are the figures in ANSI/SAAMI Z299.4, as already recorded in the SAAMI sections of our 7mm-08 Rem and .308 Win guides. Pressures are as SAAMI lists them.

Measure	7mm-08 Rem	.308 Win
SAAMI name	7MM-08 REMINGTON [7MM-08 REM]	308 WINCHESTER [308 WIN]
Drawing issued / revised	04/21/1980 / 02/18/2022	05/29/1979 / 06/03/2022 (test barrel drawing issued 05/20/1980, revised 07/12/2023)
Maximum average pressure (transducer)	61,000 psi	62,000 psi
Crusher pressure	None listed in our 7mm-08 guide	52,000 CUP
Cartridge overall length	2.530 in min to 2.800 in max	2.490 in to 2.810 in
Case length	2.035 in (−.020)	Not yet verified (not in our .308 guide)
Bullet diameter (as SAAMI prints it)	.2845 in (−.0030)	Not yet verified (not in our .308 guide)
Bore / groove diameter	Not yet verified (not in our 7mm-08 guide)	.300 in / .308 in
Twist and grooves	1 in 9.50 in, right-hand (marked optional), 6 grooves	12.00 in right-hand twist, 4 grooves
SAAMI velocity test barrel	24 in standard rifle test barrel (SAAMI’s general statement; not among its listed exceptions)	24.000 in, 12.00 in twist, 4 grooves

SAAMI measures pressure by transducer (psi) and, for some cartridges, by crusher (CUP). Compare psi with psi and CUP with CUP, never across. A “None listed” row means our guide records no figure; it is not a statement about the cartridge.

Load ranges by maker and test barrel

Each line groups one maker’s loads that share a test barrel, so a velocity is only ever shown with the barrel it was measured in. Ranges are bullet weight and muzzle velocity as the maker page prints them. Do not read across makers: their barrels and bullets differ. For how barrel length moves velocity, see our barrel length vs velocity data.

Same maker, same line, both cartridges

Where one maker sells the same product line in both cartridges, the loads are listed side by side exactly as the maker pages print them. We match lines by the maker’s own product-line name in our guide tables. Compare only within a row, and check the test barrel in each cell.

What the sources say when you choose

These are points taken from the figures above, each with the page it rests on. They are not recommendations or scores.

If pressure rating is your question: SAAMI lists a maximum average pressure of 61,000 psi by transducer for 7mm-08 Rem and 62,000 psi by transducer (plus 52,000 CUP by crusher) for .308 Win. Source: ANSI/SAAMI Z299.4.
If bullet weight is your question: the 7mm-08 Rem loads in our table run from 120 gr (Federal Fusion Rifle F708FS2) to 150 gr (Federal Power-Shok Rifle 708CS). The .308 Win loads run from 110 gr (Nosler Varmageddon 40272) to 205 gr (Federal Subsonic 308SUB1). Sources: those maker pages.
If you want to see the printed velocities: the slowest and fastest 7mm-08 Rem muzzle velocities in our table are 2,650 fps, test barrel not listed (Federal Power-Shok Rifle 708CS) and 3,000 fps, test barrel not listed (Federal Fusion Rifle F708FS2). For .308 Win they are 1,000 fps, test barrel not listed (Federal Subsonic F308TF3SUB) and 3,150 fps, 24 in test barrel (Nosler Varmageddon 40272). These come from different barrels and bullets, so we show them side by side without subtracting.
If you are comparing against a box or a chronograph: of the 7mm-08 Rem loads, 11 list 24 in, 8 with no test barrel listed; of the .308 Win loads, 45 with no test barrel listed, 33 list 24 in, 7 list 26 in, 1 list 13 in. A shorter barrel than the one a maker lists will likely give lower velocities than the box; see our barrel length vs velocity data. Source: ANSI/SAAMI Z299.4 and the maker pages in our guides.
If chamber fit is your question: SAAMI publishes a separate cartridge drawing for each, with case length 2.035 in (−.020) for 7mm-08 Rem and Not yet verified (not in our .308 guide) for .308 Win, and cartridge overall length 2.530 in min to 2.800 in max and 2.490 in to 2.810 in. Check the cartridge named in your firearm’s manual or marked on its barrel. Source: ANSI/SAAMI Z299.4.

Not yet verified

Makers and loads missing from either guide’s table (for example Winchester or SIG Sauer, where a guide says so) are listed in the “Not yet verified” section of that guide.
SAAMI reference velocities are not copied in our guides, because the PDF text does not clearly pair each weight with its velocity.
A dash in the range table means the maker has no load in that guide’s table, not that the maker sells none.
Maker status (in stock, discontinued) is not shown here. See each guide for the status wording on the maker pages.
Prices, recoil, accuracy and hands-on results are not in our data, so this page says nothing about them.

See the full tables in our 7mm-08 Rem ammo and .308 Win ammo, the barrel length vs velocity data, .270 Win vs .308 Win, .308 Win vs .30-06, 7mm Rem Mag vs 7mm PRC, .308 Win barrel length vs velocity, the new ammo of 2026, all ammo releases and all comparisons.

Frequently asked questions

What is the SAAMI maximum pressure for 7mm-08 Rem and .308 Win?

SAAMI lists 61,000 psi (transducer) for 7mm-08 Rem, and 62,000 psi (transducer), and 52,000 CUP (crusher) for .308 Win, in ANSI/SAAMI Z299.4.

Which test barrel do the makers list?

It varies by maker and load. Our tables show the barrel each maker page lists next to every velocity, and many pages list none. See the ranges table above.

Which is better, 7mm-08 Rem or .308 Win?

We don't rate or rank cartridges. This page copies maker-page figures and SAAMI specs side by side, and it does not cover price, recoil or hands-on results.

Where do these numbers come from?

From our own ammo guides (7mm-08 Rem ammo and .308 Win ammo), which copy maker product pages, and from ANSI/SAAMI Z299.4.
