300 Win Mag Review
The great thing about 300 Win Mag is that it’s not just a round for people interested in ringing steel at greater distances. It’s versatile enough to be good for hunting big game, and it enjoyed all the advances of technology Winchester had access to at the time of its creation. This is a fascinating magnum cartridge with a lot to offer.
300 Win History and Purpose
Winchester designed 300 WM in 1963 for hunting. They created it as a more versatile magnum cartridge capable of fitting in shorter actions. The cartridge was based on the 375 H&H Magnum, which is a larger cartridge. It was first offered in Winchester’s Model 70 bolt-action rifle. Although it didn’t take off with lightning speed, it earned a fairly dedicated following.
Interestingly, 300 Win was developed toward the tail end of a string of new cartridges being produced by Winchester. In the preceding years, Winchester came out with the 264 Winchester Magnum, 338 Winchester Magnum, and 458 Winchester Magnum. All came before the venerable 300 Win arrived on the scene. Some ammo aficionados believe it was the creation of the 7mm Remington Magnum that spurred Winchester to come up with the 300 Win, and it’s certainly possible. Remington launched the 7mm Remington Magnum in 1962 and it was extremely popular. Whatever the reason for the invention of the 300 WM, magnum lovers are grateful.
At the time of this writing, 60 years have passed since the 300 Win was first introduced. As time has gone by, 300 Win Mag has earned a well-deserved reputation as a stellar big game cartridge. Quite a few long-range shooters also enjoyed it. Then there’s the fact it’s seen quite a bit of military use as well. When it comes to versatility, 300 Win delivers.
Pros and Cons of 300 Win Mag vs 30-06 Springfield

30-06 Springfield Review
The 30-06 Springfield saw its first widespread use in the military, but it quickly became a favorite of big game hunters, too. This is a cartridge with more than a century of history backing it. Although they designed it in an era long past, it’s benefitted from all our advances in technology.
30-06 Springfield History and Purpose
The 30-03 Springfield is the parent cartridge of the 30-06 Springfield. The reason behind the creation of the 30-06 Springfield was to come up with a faster, lighter cartridge than what the military was using (that’d be the aforementioned 30-03 Springfield). It ended up staying in regular use by our nation’s military from its inception in 1906 through the 1970s, which is when the AR platform took over.
Originally, this cartridge was designated the “cartridge, ball, caliber .30, Model of 1906.” That ended up becoming M1906 and eventually it became 30-06 Springfield. It was first chambered in the M1903 Springfield rifles as the military altered guns to make them work with the newer cartridge. Then the 30-06 Springfield extended to guns like the M1917 Enfield, M1 Garand, and BAR (Browning Automatic Rifle). Today it’s mostly offered in bolt-action rifles, although there are some lever-action 30-06 Springfield guns as well.
In modern times, the 30-06 Springfield has become the round many hunters count on. It has the deserved reputation of being capable of taking any game in North America and delivers fantastic energy on target. It’s a versatile cartridge on its own right, but can it compete with 300 Win?
Pros and Cons of 30-06 Springfield vs 300 Win Mag
- Recoil – 30-06 Springfield produces less felt recoil than 300 Win Mag, which means a more comfortable to fire experience, comparatively.
- Rifle Size – Many rifles chambered in 30-06 Springfield are more portable and easier to maneuver than many chambered in 300 Win.
- Track Record – 30-06 Springfield has proven itself for more than a century, and can be used on all game animals in North America. Of course, it’s also proven itself in combat.
- Case Capacity –The 30-06 Springfield is the same overall length as 300 Win Mag, but with significantly less case capacity.
- Effective Range – The 30-06 Springfield doesn’t have as long an effective range as 300 Win does.
- Terminal Ballistics – The 30-06 Springfield produces a smaller wound cavity than 300 Win, meaning that although it’s effective, it’s outdone by the 300 Win.

Ballistics Comparison: 300 Win vs. 30-06 Springfield
Although the 300 Win and 30-06 Springfield are both .30 caliber rounds, they have a lot of differences. This is due largely to the major difference in case capacity between the two. Sure, they have the same bullet diameter and overall length, but that doesn’t mean their ballistic performance matches. Which is better? Check out these comparisons before you decide.
To compare cartridges beyond 100 yards, we’re going to look at a few different loads. First, let’s consider Barnes VOR-TX 300 Win 180 grain TTSX with a ballistic coefficient of 0.484 against Remington Core-Lokt 30-06 Springfield 165 grain Polymer Tipped with a ballistic coefficient of 0.447.
|Distance (yards)||Barnes VOR-TX 300 Win 180 grain TTSX Velocity (fps)||Barnes VOR-TX 300 Win 180 grain TTSX Energy (ft-lbs)||Remington Core-Lokt 30-06 Springfield 165 grain Polymer Tipped (fps)||Remington Core-Lokt 30-06 Springfield 165 grain Polymer Tipped (ft-lbs)|
As you can see in the ballistic table above, the two cartridges start out with similar muzzle velocities, but the energy produced at the muzzle is far greater for the 300 Win. Down range, they lose velocity at a similar pace, with the 300 Win maintaining a small lead over the 30-06 Springfield. As for energy, the 300 Win stays a minimum of 500 ft-lbs—or more—above the energy produced by the 30-06 Springfield for the entire distance of 500 yards. What we can see is that while the two cartridges might produce similar velocities, there is simply no comparison for energy.
If we change over to target loads and compare Hornady Match 300 Win 195 grain ELD Velocity with a ballistic coefficient of 0.584 and Sellier & Bellot 30-06 Springfield 150 grain FMJ with a ballistic coefficient of 0.290? Does it stay the same, or do the results look different?
|Distance (yards)||Hornady Match 300 Win 195 grain ELD Velocity (fps)||Hornady Match 300 Win 195 grain ELD Energy (ft-lbs)||Sellier & Bellot 30-06 Springfield 150 grain FMJ Velocity (fps)||Sellier & Bellot 30-06 Springfield 150 grain FMJ Energy (ft-lbs)|
The differences are even more obvious comparing these two loads. 300 Win has a serious edge over 30-06 Springfield, at least as far as producing more velocity and energy. Let’s consider trajectory for the same two loads:
|Distance (yards)||Hornady Match 300 Win 195 grain ELD Drop (inches)||Hornady Match 300 Win 195 grain ELD Wind Drift (inches)||Sellier & Bellot 30-06 Springfield 150 grain FMJ Drop (inches)||Sellier & Bellot 30-06 Springfield 150 grain FMJ Wind Drift (inches)|
As you can see, 300 Win doesn’t experience as precipitous a drop rate as 30-06 Springfield. It also doesn’t drift as much. That’s both because it has a greater case capacity, which translates to more powder, and due to the heavier bullet. Is it because they created 300 Win Mag almost six decades after 30-06 Springfield, or is it simply because they were originally made for different reasons?
If you choose your cartridge based entirely on the ballistics tables, you’re likely to decide 300 Win is the clear winner. After all, it’s faster and delivers a lot more energy on target. But does that really mean it’s the better cartridge?
Our Take – 300 Win vs. 30-06 Springfield
What it comes down to is what you’re going to use the gun for. If you’re into true long-range hunting or long-range precision work, you’re going to lean toward 300 Win. However, if you just want a reliable hunting rifle capable of taking a wide variety of game within a few hundred yards, 30-06 Springfield might be perfect for you.
Both the 300 Winchester Magnum and 30-06 Springfield are niche guns, of a sort. Each cartridge holds a certain appeal to hunters that tends to be range and game specific. Outside the hunting world, 30-06 Springfield often loses much of its appeal. That’s where 300 Win shines, in those areas outside hunting where ringing steel at impressive distances is the goal. Yes, it’s also stellar for making long, lethal shots on elk, but that is part of what makes 300 Win an infinitely versatile cartridge. When it comes right down to it in the battle of 300 Win Mag vs. 30-06 Springfield, 300 Win…wins.
