7mm-08 ammo compared with .243, 6.5 Creedmoor and .270: Remington Core-Lokt muzzle velocity and energy at 300 yards

7mm-08 Ammo: Best Loads for Deer, Elk and Light Recoil

The default 7mm-08 ammo for deer is a 140 grain soft point at about 2,860 fps. For elk, step to a tougher bonded, copper or 150 grain bullet.

Safety note. Fire only ammunition marked 7mm-08 Remington in a rifle chambered for it. It is not the same cartridge as the 7mm Remington Magnum. Velocities below are each maker’s published figures from its own test barrel, and your rifle will differ. Check your state’s hunting rules. No link on this site earns us a commission.

7mm-08 ammo is factory-loaded 7mm-08 Remington, a .308 Winchester case necked down to hold a 7mm bullet. It kicks less than a .308 and, by 300 yards, carries about as much energy as a 130 grain .270, which makes it one of the most sensible deer cartridges made. It just has a name that sounds like a tax form.

So what does the name mean? A hyphen and a zero walk into a gun store. The “7mm” is the bullet, and the “-08” is the parent case, the .308 Winchester. Here is which 7mm-08 ammo to buy, with each maker’s own numbers, and how it compares with the .243, .270 and 6.5 Creedmoor.

A good bolt-action rifle like the savage 110 core hunter chambered in 7mm-08 is perfect for hunting because the cartridge offers excellent accuracy, flat trajectory, and effective knockdown power on deer-sized game with mild, manageable recoil. The bolt-action design adds rock-solid reliability, strength, and precision that hunters depend on in the field. Image courtesy of savage Arms.

7mm-08 Ammo at a Glance

  • SAAMI sets 61,000 psi and a 1:9.5 twist for the 7mm-08 Remington, with a .2845 inch bullet.
  • Remington lists three loads, all 140 grain at 2,860 fps. The bullet type is the only real choice.
  • By 300 yards, Remington’s 140 grain 7mm-08 Core-Lokt carries 1,490 ft-lb, about the same as its 130 grain .270.
  • Our recoil chart puts it at 17.8 ft-lb in an 8-pound rifle, between the 6.5 Creedmoor and the .308.

Why This Round Keeps Winning People Over

The 7mm-08 started life as a wildcat called the 7mm/308 around 1958, according to its Wikipedia entry. Remington put its own name on it in 1980 and chambered it in the Model 788 and Model 700. Remington’s own page calls it the “offspring” of the .308, necked down for a 7mm (.284 inch) bullet, with “a great balance of power, accuracy, and tame recoil.”

Basically, it is a short-action round that fits light rifles. Our rifle caliber chart lists its case at 2.035 inches against the .308’s 2.015. So you get .308-sized rifles with a longer, sleeker bullet up front. That is the whole trick.

The 140 Grain Is the Default, and Why

Look at Remington’s catalog and the answer jumps out. Every 7mm-08 load Remington sells right now is 140 grains, listed at 2,860 fps. Remington’s own deer advice names two of them, the Core-Lokt and the Core-Lokt Tipped.

So the real choice in 7mm-08 ammo is bullet construction, not weight. The ballistic coefficient (a rating of how well a bullet slips through air, higher is better) is where the three split. Remington lists .390 for the Core-Lokt soft point, .429 for the copper CuT and .486 for the Core-Lokt Tipped.

That shape shows up downrange. At 500 yards, Remington lists the Core-Lokt at 1,005 ft-lb, the CuT at 1,101 and the Tipped at 1,226. Same weight, same muzzle speed, and the tipped bullet arrives with 221 more foot-pounds. Remington says it plainly too: for longer shots, like mule deer country, “consider Core-Lokt Tipped.”

Here is a short list instead of fifty. I picked loads from two makers with full downrange numbers on their own pages.

7mm-08 factory loads, maker’s published figures
Load Bullet fps 300 yd ft-lb
Rem. Core-Lokt 140 gr soft point 2,860 1,490
Rem. Core-Lokt Tipped 140 gr tipped 2,860 1,664
Rem. Premier CuT 140 gr copper 2,860 1,568
Hornady Superformance 139 gr SST 2,950* 1,770
Hornady Precision Hunter 150 gr ELD-X 2,770* 1,784

From Remington’s 7mm-08 product pages (items 21337, R20039, R22339) and Hornady’s product pages (items 80573, 85578), checked October 18, 2026. *Hornady measures from a 24-inch test barrel. Remington does not list a test barrel length.

7mm-08 is not one of the cartridges on our ammo price history tracker, so this page does not list prices. On Remington’s own store, the Core-Lokt Tipped and copper CuT boxes cost more than the plain Core-Lokt.

Winchester 7mm 08 deer hunting ammunition
The 7mm-08 makes an excellent deer hunting round because it delivers a flat trajectory, solid accuracy, and enough energy and penetration to cleanly take deer at typical hunting ranges while producing mild, manageable recoil.

Deer vs. Elk

For deer, any of the 140 grain 7mm-08 ammo above will do it at normal distances. Remington’s own page says the 7mm-08 is effective on deer “out to 400-500 yards with a 140-grain controlled expansion bullet.” I would put the limit where you can keep every shot on a paper plate from a field position, cold. For most of us that is well short of what the box claims.

Elk is a different animal (literally). Colorado’s manner-of-take rule, 2 CCR 406-2-203, is a good real-world yardstick. For elk it requires a .24 caliber or larger centerfire and an expanding bullet of at least 85 grains. It also requires a rated 1,000 ft-lb at 100 yards. Every 7mm-08 load in the table clears that easily, since all of them carry more than 2,100 ft-lb at 100 yards.

Legal and ideal are not the same thing, though. For elk I would pick 7mm-08 ammo with a bullet built to hold together. That means Remington’s all-copper CuT, or Hornady’s 150 grain ELD-X. Hornady says the ELD-X “continually expands” inside about 400 yards while keeping 50 to 60 percent of its weight, and keeps 85 to 90 percent past that. Check your own state’s rules before the trip.

Recoil Next to the .243 and .308

“What kicks harder, a .243 or a 7mm-08?” The 7mm-08 does, but not by a scary amount. Our rifle recoil chart runs SAAMI’s free-recoil formula on Hodgdon maximum handloads in an 8-pound rifle. It lists the .243 at 13.4 ft-lb and the 7mm-08 at 17.8. The 150 grain .308 comes in at 20.2, and the .270 at 21.2.

So the 7mm-08 sits in a sweet spot. It gives you a 140 grain bullet with recoil under the .308 and the .270. Remington calls it “a great choice for new shooters,” and I agree, with one condition. Put it in a rifle that fits the shooter. Remember that the same chart shows a 9-pound rifle taking about 22 percent off the recoil of a 7-pound one.

How It Compares to .270 and 6.5 Creedmoor

Here are four deer rounds side by side, all from one maker’s plain soft point line so the comparison stays fair.

Four deer rounds side by side, Remington Core-Lokt
Cartridge Bullet fps 300 yd ft-lb Recoil
.243 Win 100 gr 2,960 1,089 13.4
6.5 Creedmoor 140 gr 2,700 1,347 14.7
7mm-08 Rem 140 gr 2,860 1,490 17.8
.270 Win 130 gr 3,060 1,471 21.2

Velocity and energy from Remington’s Core-Lokt product pages (items R27802, 27657, 21337, 27808), checked October 18, 2026; Remington does not list a test barrel length. Recoil is free recoil energy in ft-lb for an 8-pound rifle from the Popular Ammo rifle recoil chart, which uses Hodgdon maximum handloads, not these factory loads.

Same maker, same bullet line, four cartridges. The 7mm-08 and the .270 finish within 19 ft-lb of each other at 300 yards. Image courtesy of Popular Ammo.

Now, is a 7mm-08 more powerful than a .270? At the muzzle, no. Remington lists the .270’s 130 grain Core-Lokt at 2,703 ft-lb against 2,543 for the 7mm-08. But the 7mm-08’s heavier bullet has the better coefficient, .390 against .336, so it catches up. By 300 yards it is 1,490 against 1,471, a wash. Our 270 vs 308 page goes deeper on the .270 side of the family.

Against the 6.5 Creedmoor, the 7mm-08 Core-Lokt leaves faster and carries more energy at every distance Remington lists. The price is a little more recoil, 17.8 against 14.7 on our chart. Our 6.5 Creedmoor vs 308 page shows that the 6.5’s downrange edge comes from its bullets, not its case.

7mm-08 Ammo vs .308

This is the comparison people search for most, since one round is the other’s parent. Remington’s 150 grain .308 Core-Lokt starts stronger, at 2,648 ft-lb against 2,543 for the 140 grain 7mm-08 Core-Lokt. By 300 yards, though, the 7mm-08 is ahead, 1,490 against 1,344. It keeps that lead to 500 yards in Remington’s tables, 1,005 against 811.

So why does the smaller bullet win downrange? Because Remington lists the 7mm-08 Core-Lokt with a .390 coefficient and the .308 Core-Lokt with .314. The sleeker bullet sheds speed more slowly. Also, the 7mm-08 kicks less in our recoil chart, 17.8 against 20.2. In Remington’s catalog the .308 does offer more weights, 150 and 180 grain Core-Lokt against a single 140. For a deer rifle, though, I would take the 7mm-08 every time.

Frequently Asked Questions

What is a 7mm-08 good for?

Whitetail and mule deer, which is what Remington’s own load advice is written for, and elk with a tough bullet. Remington calls it a great choice for new shooters, and its short action makes for light, handy rifles.

Is 7mm-08 the same as 7mm Remington Magnum?

No. Our chart shows the same .2845 inch bullet, but the 7mm Rem Mag case is 2.500 inches long against 2.035, with a wider .532 inch head. Never mix them.

What twist rate is a 7mm-08?

SAAMI lists 1:9.5. That handles the 139 to 150 grain hunting bullets in the table above.

Is 7mm-08 good for long range?

For deer, Remington itself claims 400 to 500 yards with a 140 grain hunting bullet. I would rather you prove your own limit on paper first. The fastest load in the table is Hornady’s 139 grain SST, listed at 2,950 fps from a 24-inch barrel.

Final thoughts: buy the 140 grain 7mm-08 ammo your rifle groups best, use a tipped or copper bullet if the shots get long or the animals get big, and stop apologizing for not owning a magnum. Before the season, Popular Outdoorsman’s guide on how to deer hunt covers the rest of the plan.
