Historical past

7mm Remington Magnum

Many new cartridges are available in scorching after which fade with time. That’s not the case with the 7mm Rem Magazine. In addition to its flat-shooting and hard-hitting capabilities, the 7mm Remington Magnum owes a lot of its preliminary success to its launch coinciding with Remington’s introduction of the Mannequin 700 rifle in 1962. The Mannequin 700 is likely one of the hottest looking rifles in historical past and the 7mm Remington Magnum rode its recognition upon introduction. 

The 7mm Rem Magazine’s mum or dad case is the venerable .375 H&H shortened and necked right down to accommodate a .284 caliber bullet and slot in a standard-length rifle motion. On the time of its introduction, the .30/06 Springfield was the usual all cartridges have been in contrast towards. The 7mm Rem Magazine is ballistically superior to the .30/06 in each class and the brand new cartridge was an on the spot success. Since then, the 7mm Rem Magazine has turn into one of the crucial common big-game cartridges of recent time. 

.300 Winchester Magnum

Following the success of the 7mm Rem Magazine, Winchester adopted go well with with its personal magnum, introducing the .300 Win Magazine only a yr later in 1963. Just like the 7mm Rem Magazine, the .300 Win Magazine makes use of the .375 H&H case, shortened and necked down to fireplace .308 caliber projectiles. Because of the bigger case capability, the .300 Win Magazine delivers each a flatter trajectory and noticeably extra power down vary when in comparison with the 30/06.

Winchester properly supplied the brand new cartridge within the common Mannequin 70 rifle, and the .300 Win Magazine took off in recognition as nicely. Inside a number of quick years most main ammunition producers have been producing .300 Win Magazine ammo and so they nonetheless are immediately.


Ballistically talking, the 7mm. Rem Magazine and .300 Win Magazine are a lot nearer than their loyal fan bases want to admit. Provided that they each derive from the identical mum or dad case, each cartridges function comparable case capability and have some overlap in bullet weight choice. Right here’s how they stack up with a number of common masses. 

150-Grain Federal Energy-Shok

To show their similarities, the primary comparability I pulled was Federal Premium’s 150-grain Energy-Shok ammunition, as Federal masses this identical bullet for each cartridges.

7mm Remington Magnum

  • Muzzle Velocity: 3,110 fps
  • Power @300 yds: 1,969 ft-lb
  • Drop @300 yds: 10.4 inches

.300 Winchester Magnum

  • Muzzle Velocity: 3,150 fps
  • Power @300 yds: 1,975 ft-lb
  • Drop @300 yds: 10.2 inches

Sure, the .300 Win Magazine does have a mouse hair of a bonus on this comparability, however the numbers are so shut that the distinction is negligible.

Heavy-for-Caliber Bullets

One benefit the .300 Win Magazine has over the 7mm Rem Magazine is its potential to shoot heavier projectiles. Standard bullet weights for the .300 vary from 150- to- 200-grains whereas frequent bullet weights for the 7mm Rem Magazine vary between 140- and- 175-grains. Larger could sound higher however that isn’t all the time the case. Ballistic coefficient and sectional density of a bullet each play an element of their ballistic and terminal efficiency. Given the identical weight projectile, .284 bullets will sometimes have each the next B.C. and sectional density than .308 caliber bullets of equal weight, leading to higher penetration regardless of the smaller diameter bullet.

So now let’s evaluate a “heavy-for-caliber” providing from each cartridges. For the 7mm Rem Magazine, I caught with the “Massive Inexperienced” practice and chosen Remington’s 175-grain Core-Lokts. For the .300 Win Magazine, I pulled information for Hornady’s 200-grain ELD-X loaded of their Precision Hunter line.

7mm Rem Magazine, 175-grains

  • Muzzle Velocity: 2,860 fps
  • Power @300 yds: 1,958 ft-lb
  • Drop @300 yds: 7.6 inches (200-yard zero)

.300 Win Magazine, 200-grains

  • Muzzle Velocity: 2,850 fps
  • Power @300 yds: 2,563 ft-lb
  • Drop @300 yds: 7 inches (200-yard zero)

Clearly, the heavier bullet fired from the .300 Win Magazine generates considerably extra downrange power. Nevertheless, the distinction in bullet drop between the 2 is nominal. Plus, the 1,958 ft-lbs of power that the 175-grain Core-Lokt transfers at 300 yards will nonetheless ship ample power to take down a rut crazed bull elk with authority.

Ballistically talking, the 2 cartridges are very comparable when capturing the identical weight projectiles. Though, there is no such thing as a refuting the substantial further power that the .300 Win Magazine produces when capturing heavier bullets.

The .300 Win Magazine produces about 30 ft-lbs of recoil, roughly 20 % extra. For reference, a .270 Winchester generates about 20 foot-pounds of recoil.

For some, recoil generally is a deal breaker. For others, it’s a small a part of the equation. Regardless of the place you stand, the lighter recoil of the 7mm Rem Magazine offers it the sting by way of consolation and shootability. 

Including a muzzle brake or suppressor to a rifle chambered in both of those cartridges will assist scale back felt recoil.
