The current gun market in the U.S.A. is thriving with small and fast bullets. Gone are the days when people believed that heavier bullets did a better job. Now, people prioritize portability, efficiency, and perfection over the mere size of a bullet.
Today, we’ll talk about the nitty-gritty of two popular small rounds – 7mm 08 Remington and 270 Winchester. If you’re struggling to settle the 7mm 08 vs. 270 debate, this guide is for you.
Differences Between 7mm 08 Rem and 270 Win
Cartridge specifications depend on the shooter’s experience, rifle model, and shooting style. Each type of cartridge has different performance outcomes and advantages.
Ballistic performance refers to the factors that influence the launch and journey of a bullet. Here are the different ballistic parameters for these cartridges:
Velocity covers the speed at which the bullet is launched and its impact on the target. For a successful target hit, it’s important to reach the optimum velocity. If it’s too slow, the bullet won’t have the required effect on the target, and if it’s too fast with a high twist rate, it might miss the target.
On average, the 270 Win cartridges have a higher velocity than 7mm 08 Rem cartridges. Both have similar bullet weights, but the 270 Win has a higher recoil, case capacity, and velocity.
Ballistic coefficient is a bullet’s ability to overcome external resistance like wind drift. Bullets with a higher ballistic coefficient tend to perform better and reach the target regardless of the air resistance. This is an important factor for hunters or law enforcement professionals who cannot afford to miss the target.
The exact ballistic coefficient for the two types of cartridges depends on the cartridge build and design, but the 270 Win will beat the 7mm 08 cartridges on most occasions.
With that being said, it’s important to note that the difference in their ballistic coefficient values is hardly noticeable. So if this is a significant criterion for you, both 7mm 08 Rem and 270 Win cartridges should do the job.
The trajectory is the maximum horizontal difference covered by a bullet when fired from a gun. A decent trajectory is essential to hit your target, especially at greater distances. The biggest benefit of both these cartridges is that they have an almost flat trajectory, meaning there’s hardly any dip in the elevation level until the end as the bullets traverse.
Once again, the 270 Win triumphs over the 7mm 08 Rem. However, like most parameters, there isn’t a stark difference here either. The only visible difference kicks in after the first 200 yards, where the 270 Win takes the lead with its flatter trajectory and a lower elevation dip, causing it to end at a few yards ahead of the 7mm 08 Rem.
Stopping Power and Impact
You want a round with enough kinetic energy to penetrate the target. The average kinetic energy for 270 Win cartridges is slightly higher than 7mm 08 Rem cartridges. However, the actual ability of a bullet to make a powerful impact largely depends on its design and expansion after hitting the target.
So, if you’re comparing 7mm 08 vs. 270 cartridges based on kinetic energy alone, the latter has the upper hand, but the real stopping power and impact will depend on the overall construction of the bullet and the amount of gunpowder used.
Stopping power and penetration goes hand in hand. A bullet with a higher impact on the target will naturally penetrate deeper into it.
Another factor influencing a bullet’s penetration capacity is its sectional density. A higher sectional density allows bullets to pierce through more layers, depending on the bullets’ weights and diameters.
With a slightly higher diameter and weight, the 270 Win has a higher sectional density, giving it more penetration power than a 7mm 08 Rem.
Recoil and Muzzle Velocity
Determining the muzzle velocity just from the cartridge is difficult, but who’s to say you can’t track their recoil? Recoil is basically the kickback or backward force the shooter experiences when the bullet is fired from the rifle. While it might not be a big deal for experienced shooters, beginners will almost always prefer a low recoil.
Thanks to its significantly lower recoil, a 7mm 08 Rem cartridge beats the 270 Win in this race. The exact value depends on the shooting style and rifle, but it’s usually at least 5 pounds of recoil less than a 270 cartridge.
Simply put, the 7mm 08 Rem will have a lesser impact on your hands and shoulder, making it easy for you to prepare for the next round.
Which Is More Affordable: 7mm 08 Rem or 270 Win?
The cost of a 7mm 08 Rem and 270 Win are relatively the same. However, the 270 Win currently has a higher demand and a slightly more affordable average price. Also, you’re more likely to find a wide variety of these hunting cartridges, given their high demand.
What Are 7mm 08 Rem and 270 Win Used For?
270 Win cartridges are best used as hunting rounds, especially for mule deer, hogs, or any larger game. On the other hand, 7mm 08 Rem have lighter bullets and are best for intensive training sessions or flat shooting.
Which Rifle Is Best for These Cartridges?
The rifle weight and design largely determine which cartridge you should use. If you’re using compact rifles, go for the 7mm 08 Rem. But if you have a bulky, heavy deer rifle, use a 270 Win.
Your shooting experience and efficiency largely depend on your cartridges. That’s why it’s important to choose efficient and easily available cartridges. Our research on 7mm 08 vs. 270 cartridges suggests that both are similar in every aspect. Although a 270 Win might outperform a 7mm 08 Rem on paper, there’s a negligible difference in their actual performance.
