The 7mm Remington Magnum (SAAMI abbreviated name 7mm REM MAG) is a belted, .284-inch-bullet magnum rifle cartridge that Remington introduced in 1962 alongside the Model 700 rifle, and it is used mainly for long-range big game hunting on deer, pronghorn, elk and similar game.
This page is a ballistics chart first. Every velocity, energy and ballistic coefficient below was copied from the manufacturer’s own page for that exact item number, and every energy figure was re-derived from grains × fps² ÷ 450437 before it was published. All nine loads agreed with their makers’ published energy to better than 0.5 percent, and velocity and energy fall monotonically down every published range. Hilltop Armory LLC is a retailer and has tested none of this ammunition.
Why the test barrel length is in the table
A muzzle velocity without a barrel length is not a specification. SAAMI’s standard velocity and pressure test barrel for 7mm Remington Magnum is 24.000 in ± .010 (609.60 mm), six grooves, 9.50-inch right-hand twist, so 24 inches is the reference length for this cartridge. Nosler and Sellier & Bellot publish a test barrel length for the loads below, and it is 24 inches in both cases. Federal and Remington publish no test barrel length on their item pages for these loads, so their figures sit in a table of their own further down and must not be read across against the 24-inch table.

Provenance: the bullet weights, bullet names, velocities, energies, ballistic coefficients and test barrel lengths above are the manufacturers’ own published figures, read from nosler.com and sellier-bellot.cz on 20 September 2026. The two Sellier & Bellot rows marked “converted” are unit conversions Hilltop Armory made from S&B’s own published metric figures: 958 m/s and 4,176 J for the 140-grain SP, 848 m/s and 4,027 J for the 173-grain SPCE. The grain weights, coefficients and the 610 mm barrel in those rows are S&B’s. Nosler publishes no ballistic coefficient for its 7mm Rem Mag ammunition, and a ballistic coefficient is measured rather than calculated, so those cells read “not published” rather than being filled.

Provenance: Nosler’s published figures for these three item numbers, read from nosler.com on 20 September 2026. Nosler publishes these tables out to 800 yards; the chart above stops at 500 because that is where the comparison with the other makers on this page ends, not because the data does. Sellier & Bellot publishes its downrange data in metres rather than yards, so it cannot share this table: S&B lists its 173-grain SPCE at 767, 691, 619 and 551 m/s and 3,296, 2,672, 2,145 and 1,703 J at 100, 200, 300 and 400 metres, and its 140-grain SP at 819, 691, 575 and 470 m/s and 3,051, 2,171, 1,505 and 1,004 J over the same distances. Those are S&B’s own units, left unconverted.

Federal and Remington: full range tables, test barrel not published
These four loads have complete published velocity and energy curves, but neither Federal nor Remington states a test barrel length on the item page. Because the barrel is unknown, these figures are not directly comparable with the 24-inch table above: a difference in barrel length can move a magnum velocity by more than the difference between two loads. Read this table against itself, not against the first one.

Provenance: Federal’s and Remington’s own published figures for these item numbers, read from federalpremium.com and remington.com on 20 September 2026, taken from the chart data behind the rendered tables so that the zero-range cells are not dropped. Both makers publish to 500 yards and no further, and neither publishes a test barrel length for these items.
What these numbers mean for a shot
The shape of the cartridge is visible in the first table. Across a 33-grain spread of bullet weight, from the 140-grain Sellier & Bellot SP at 3,143 fps to the 173-grain SPCE at 2,782 fps, muzzle energy moves only from 3,080 to 2,970 ft-lb. The 7mm Rem Mag trades velocity for bullet weight at close to constant muzzle energy, so choosing between loads is a choice about what the bullet does, not about how much energy leaves the barrel.
Ballistic coefficient is what separates them past 300 yards. The Federal Premium 162-grain ELD-X carries the highest published coefficient on this page at 0.631 G1, and from 2,940 fps it still shows 2,239 fps and 1,803 ft-lb at 500 yards, keeping 76 percent of its muzzle velocity. The Remington Core-Lokt 150-grain leaves 170 fps faster at 3,110 fps and arrives at 500 yards 373 fps slower, at 1,866 fps and 1,160 ft-lb, because Remington publishes 0.346 for it. A soft point and a long tipped boat-tail diverge with distance, and the muzzle row will not tell you that; the range rows will.
For a shooter setting a scope, Nosler’s 200-yard-zero figures are the practical ones. With the 140-grain AccuBond Trophy Grade zeroed at 200 yards, Nosler publishes the bullet 1.3 inches high at 100, 6.0 inches low at 300 and 17.4 inches low at 400. The 160-grain AccuBond gives up 0.4 inches at 300 yards and 1.1 inches at 400 against the 140, and returns 172 ft-lb more at 400. Those are Nosler’s numbers from Nosler’s 24-inch test barrel, not a prediction for any particular rifle.
Among the copper and lead-free choices, the Nosler E-Tip 150-grain is the one whose maker marks it lead-free on the spec sheet; it leaves at 3,000 fps for 2,997 ft-lb and still holds 1,494 ft-lb at 500 yards. The Federal Premium 145-grain Barnes LRX is the fastest of the three Federal loads at 3,125 fps, though at 0.449 G1 it sheds velocity faster than the heavier tipped loads do, while the Federal Premium Terminal Ascent 155-grain sits between the ends of the weight range at 3,000 fps, 0.586 G1 and 0.300 G7, with 1,727 ft-lb still in hand at 500 yards.
Sectional density is arithmetic rather than a measurement, and at this bore it follows bullet weight directly: grains divided by 7,000, divided by the square of the .284-inch bullet diameter, gives 0.248 at 140 grains, 0.257 at 145, 0.266 at 150, 0.275 at 155, 0.283 at 160, 0.287 at 162 and 0.306 at 173. Sellier & Bellot publishes 0.248 and 0.306 for its two loads, which is the same arithmetic; the rest are computed here, not quoted from a maker.
Each maker also states what it built a load for, and that classification is the ceiling on any use claim a retailer can make. Nosler lists all three of its loads above as intended for deer-sized game. Sellier & Bellot describes the 173-grain SPCE as appropriate for light to medium game and gives its suggested use as hunting. Federal and Remington list theirs as big game and long range. None of these makers publishes a tested group size, an extreme spread, a penetration depth or an expanded diameter for these items, so this page publishes none of those either.
Twist rate, chamber and pressure
The following comes from SAAMI’s published centerfire rifle standard, ANSI/SAAMI Z299.4, and applies to the cartridge rather than to any one load.
Designation. The full SAAMI name is 7mm Remington Magnum and the abbreviated name is 7mm REM MAG. It is a different cartridge from 7mm Remington Ultra Magnum, 7mm Remington Short Action Ultra Magnum, 7mm-08 Remington, 7mm Weatherby Magnum, 7mm Winchester Short Magnum, 7mm Precision Rifle Cartridge and 7mm Mauser (7×57). Each of those is a separate SAAMI cartridge with its own chamber, and none of them interchanges with this one. Ammunition marked 7mm Remington Magnum goes in a rifle marked 7mm Remington Magnum, and nowhere else.
Twist and bore. SAAMI’s chamber drawing specifies six grooves and a 9.5-inch right-hand twist as optional, with a .277-inch bore diameter, a .2837-inch groove diameter and a .2845-inch bullet diameter. The standard velocity and pressure test barrel uses the same 9.50-inch right-hand twist over its 24.000-inch length. Nosler publishes a 1-9.5 inch test barrel twist for its 7mm Rem Mag ammunition. Neither SAAMI nor any maker on this page publishes a minimum twist rate for an individual load, so if you intend to shoot a long, heavy, high-coefficient 7mm bullet, check the twist rate your rifle’s maker specifies instead of assuming the rifle will stabilize it.
Chamber and cartridge length. SAAMI gives a maximum cartridge overall length of 3.290 in and a minimum of 3.150 in for this cartridge. The case is belted. The drawing was issued on 21 April 1980 and last revised on 6 December 2021, and SAAMI states that its drawings are subject to change.
Pressure. Maximum average pressure for 7mm Remington Magnum is 61,000 psi measured by transducer, or 52,000 CUP measured by crusher. SAAMI’s maximum probable lot mean is 62,500 psi and its maximum probable sample mean is 64,800 psi. SAAMI publishes one pressure standard for this cartridge and no +P variant, and Sellier & Bellot marks both of its loads above as “+P Ammunition: No”. Where a loader marks a 7mm Rem Mag load as a step above standard pressure, that is the loader’s own designation rather than an industry ceiling, and such a load belongs only in the specific actions that loader names.
Platform and legal limits. This is a long-action magnum bolt-rifle cartridge, and the rifle must be chambered and marked for it. Nosler marks these items as carrying a California Proposition 65 warning and as subject to shipping restrictions. Ammunition cannot be sent to every address in the United States: several states and localities require delivery to a licensed vendor or impose their own permits, so check the rules where you live before you order. Hunting regulations, including non-toxic ammunition requirements and minimum caliber or energy rules, are set by each state’s wildlife agency and vary by species.
7mm Rem Mag vs 300 Win Mag: the SAAMI comparison
These two belted magnums are cross-shopped more than any other pair in the American catalogue, and almost every comparison of them sets one maker’s 7mm table against another maker’s 300. ANSI/SAAMI Z299.4 measures both in a 24.000-inch standard test barrel, so the rows below are the only ones on this page that are directly comparable.
Scroll the table sideways for the remaining columns.
| SAAMI specification | 7mm Remington Magnum | 300 Winchester Magnum |
|---|---|---|
| Maximum average pressure | 61,000 psi | 64,000 psi |
| Standard test barrel length | 24.000 in | 24.000 in |
| Test barrel twist rate | 1 turn in 9.50 in | 1 turn in 10.00 in |
| Test barrel groove diameter | .2837 in | .308 in |
| Light reference load | 139 gr — 3,150–3,230 fps / 3,062–3,219 ft-lb | 150 gr — 2,635–3,390 fps / 2,312–3,827 ft-lb |
| Standard hunting weight | 160 gr — 2,940 fps / 3,070 ft-lb | 180 gr — 2,950–3,080 fps / 3,478–3,791 ft-lb |
| Heaviest reference load | 175 gr — 2,750–2,850 fps / 2,938–3,156 ft-lb | 220 gr — 2,665 fps / 3,469 ft-lb |
The 300 Winchester Magnum is standardised at 64,000 psi against the 7mm Remington Magnum’s 61,000, and it takes heavier bullets: 220 grains where the 7mm stops at 175. At every matched point the 300 carries more energy, and that is what people mean when they call it the bigger cartridge.
What the pressure and energy rows leave out is sectional density and bullet shape. A 175-grain .284-inch bullet is long for its diameter in a way a 180-grain .308 is not, and that is the 7mm’s argument. SAAMI publishes no ballistic coefficients, so that argument has to be made from the makers’ own figures, and only Sellier & Bellot publishes one for the loads charted above: 0.231 G1 for its 140-grain SP and 0.376 G1 for its 173-grain SPCE.
We stock the other side of this comparison too: 300 Win Mag ammo, 30-06 ammo.
7mm Rem Mag ballistics questions
How much will a 7mm Rem Mag drop at 300 yards?
Nosler publishes −6.0 inches for its 140-grain AccuBond, −6.4 inches for the 160-grain AccuBond and −6.5 inches for the 150-grain Expansion Tip, all from a 24-inch test barrel with a 200-yard zero. Those are the only three drop figures on this page, because Federal’s long-range chart states a 100-yard zero while its own numbers read zero at 200 yards, and a drop figure whose zero is in doubt is not worth publishing.
Is a 7mm more powerful than a 308?
Yes, by a wide margin, and the pressure standard is most of the reason. SAAMI standardises the 7mm Remington Magnum at 61,000 psi against the 308 Winchester’s 62,000, but the 7mm burns far more powder behind the bullet: its 150-grain reference loads run 2,990–3,100 fps where the 308’s run 2,800–2,980, and its 175-grain loads run 2,750–2,850 fps where the 308’s 180-grain reference is 2,600.
Does a 7mm Rem Mag kick harder than a 30-06?
Recoil is not a published specification and it cannot be read off a ballistics chart: free recoil depends on rifle weight and powder charge, and no maker on this page publishes either. The published inputs point one way. SAAMI lists the 7mm Remington Magnum at 61,000 psi with 160-grain loads at 2,940 fps; the 30-06 Springfield at 60,000 psi with 165-grain loads at 3,015 fps and 180-grain at 2,690–2,860. The two are closer on paper than the word magnum suggests.
What caliber is a 7mm Rem Mag equivalent to?
It is a .284-inch bullet in a belted magnum case. The SAAMI standard test barrel has a .277-inch bore and a .2837-inch groove, rifled one turn in 9.50 inches. Nothing else in common American use occupies exactly that slot; the 280 Remington is the same bullet in an unbelted case, and the 300 Winchester Magnum is the same case class with a .308-inch bullet.
Why are some 7mm Rem Mag loads missing from the chart?
Because their makers do not publish figures for them. Winchester’s and Browning’s product pages for their 7mm Rem Mag loads returned “There is no ballistics data available at this time” when they were checked on 20 September 2026. SIG SAUER’s figures could not be confirmed on sigsauer.com on the same date. Buffalo Bore publishes chronograph velocities from named production rifles with barrels from 21.5 to 24 inches rather than one standard barrel, so they cannot be dropped into a single-barrel table. A blank is a finding, not a gap to fill.
