The 7 mm-08 Remington is almost a direct copy of a wildcat cartridge developed around 1958 known as the 7mm/308. As these names would suggest, it is the .308 Winchester case necked down to accept 7 mm (.284) bullets with a small increase in case length. Of cartridges based upon the .308, it is the 3rd most popular, behind only the .308 itself and the .243 Winchester.[1] In 1980, the Remington Arms company popularized the cartridge by applying its own name and offering it as a chambering for their model 788 and model 700 rifles.



This cartridge is relatively inexpensive to reload and very brass-friendly, meaning that cases tend to last through a succession of reloads.

The 7 mm-08 Remington is generally considered a good choice for handloading. The popularity of the cartridge means there is a fairly wide selection of factory-loaded loads, making it a very good choice even for those who do not handload. Bullets weighing from 100 to 175 grains are available. Bullets in the 130-150gr range will suit most hunting applications while long range shooters will opt for the heaviest bullets to take advantage of their high ballistic coefficients. Medium burning rifle powders usually work best in the 7mm-08.


With the wide range of bullet weights available, the 7mm-08 is suitable for "varminting, game-hunting, silhouette, and long-range shooting."[2] It is also eminently suitable for plains game."[1] For long-range target and metallic silhouette shooting, the "plastic-tipped 162gr A-Max has proven to be very accurate, with an impressive 0.625 BC. This A-Max bullet, and the 150gr Sierra MK (i.e., MatchKing), are also very popular with silhouette shooters."[2]

The 7 mm-08 Remington works well in most hunting environments, including dense forest areas and large open fields. It has a slightly flatter trajectory than the .308 Win. and .30-06 Springfield at similar bullet weights because the slightly smaller-diameter 7mm bullet generally has a better ballistic coefficient, and is thus less affected by drag and crosswind while in flight. Bullet energy at 100 yards is four times greater than that of the .44 Magnum while recoil is only slightly more than the .243 Win.

Wayne van Zwoll of Petersen's Hunting magazine wrote: "Efficient case design and a bullet weight range suitable for most North American big game make the 7mm-08 a fine choice for all-around hunting. Civil in recoil, it's a perfect match for lightweight, short-action rifles. It has also courted favor on metallic silhouette ranges, where its 140-grain bullets reach 500-yard targets faster and with as much energy as 150-grain .308s." [3] He also described it as "deadly" for elk.

Cartridge Comparisons

Anything a 7mm can do, a .30 caliber of comparable sectional density and ballistic coefficient can also do. The catch is, in order to send a .30-caliber slug over a trajectory as flat as that 7mm bullet, about 20 percent more recoil is going to be generated. . . . [A bullet in] 7mm produces clearly superior downrange performance in terms of delivered energy and trajectory at any given recoil level [compared to a bullet in .30 caliber].[4]

Because of the 7mm (.284) caliber's greater ballistic co-efficient the 7mm-08 tends to lose less energy as it heads down range. Beyond 100 yards a 7mm-08 projectile in the 140 grain range is able to carry at lot more energy than its bigger sibling the .308. Hornady released a 7mm(.284)caliber projectile weighing an odd 139 grains. this particular bullet has set the benchmark for this caliber of bullet retaining great energy beyond 100 yards. within 100 yards the 7mm round fired out of a 7mm-08 is able to kill game as effectively as a .308 and beyond 100 yards is more effective in that it holds greater energy and also a flatter trajectory. at the velocities this caliber produce it still allows great expansion at ranges up to and beyond 500 yards.

The 7mm-08 invites ballistic comparison with the veteran, highly esteemed 7x57mm Mauser and to some extent the 7x64mm. With bullets up to 150 grains the compact 7mm-08 marginally outperforms both older, longer cartridges, and is thus more efficient. But the 7mm-08's performance begins to drop off when bullet weights exceed 150 grains and the larger case capacities of the 7x57mm Mauser and the 7x64mm permit the required larger loads of slow-burning powder (which then necessitate longer barrels).

In January 2002, Dave Anderson of Guns Magazine compared four of his favorite 7mm cartridges (7x57mm Mauser, .280 Remington, .284 Winchester, and 7mm-08 Rem.), and concluded:

But consider everything -- performance, recoil, rifle size and weight, rifle availability, ammunition availability and selection -- and the winner, rather to my surprise, is the 7mm-08 Remington. Ten years ago, even five years ago, I wouldn't have said that. But this efficient, effective little cartridge is a good one, and it's going to be around for a long time.[5]

Jeff Cooper was impressed enough by the 7mm-08 to give it unqualified support for use in a scout rifle -- "A true Scout comes in .308 or 7mm-08".[6 ]


Since the 7mm-08 Rem. is fairly popular, most major hunting firearm manufacturers in the USA have one or more bolt action rifles chambered for the round. Browning offers it in several versions of their box fed lever-action rifle, the BLR. Additionally, in 2009 Browning introduced a 7mm-08 version of their gas-operated semiautomatic rifle called the BAR ShortTrac Stalker.

The caliber has also found some loyal adherents in Europe.
