7mm Rem Mag Vs 30-06 Ballistics Chart
Introduction
When it comes to hunting, choosing the right ammunition is crucial. Two popular choices among hunters are the 7mm Remington Magnum and the .30-06 Springfield. Both cartridges have been around for decades and offer great ballistics for long-range shooting. However, which one is better? In this article, we will compare the 7mm Rem Mag vs 30-06 ballistics chart to help you make an informed decision.
What is a Ballistics Chart?
A ballistics chart is a graph that shows the trajectory of a bullet over a certain distance. It takes into account the muzzle velocity of the bullet, the ballistic coefficient, and the drag caused by air resistance. By using a ballistics chart, hunters can estimate the drop and drift of their bullets at different ranges, allowing them to make accurate shots.
The 7mm Remington Magnum
The 7mm Remington Magnum (7mm Rem Mag) was introduced in 1962 and quickly gained popularity among hunters and long-range shooters. It is a centerfire cartridge with a bullet diameter of 7.2mm and a case length of 64mm. The 7mm Rem Mag has a high muzzle velocity and a flat trajectory, making it ideal for long-range shooting.
The .30-06 Springfield
The .30-06 Springfield (30-06) has been around since 1906 and has established a reputation as a versatile cartridge for hunting and military use. It has a bullet diameter of 7.62mm and a case length of 63mm. The 30-06 has a slower muzzle velocity than the 7mm Rem Mag but offers great stopping power and accuracy.
7mm Rem Mag vs 30-06 Ballistics Chart
Now, let's compare the ballistics of the 7mm Rem Mag and the 30-06. We will use Federal Premium Ammunition as our example for both cartridges.
Muzzle Velocity
The muzzle velocity is the speed at which the bullet leaves the barrel. The 7mm Rem Mag has a muzzle velocity of 3,100 feet per second (fps) with a 150-grain bullet, while the 30-06 has a muzzle velocity of 2,900 fps with the same weight bullet. This means that the 7mm Rem Mag has a flatter trajectory and less bullet drop at long ranges than the 30-06.
Energy
The energy of a bullet is the amount of force it delivers upon impact. The 7mm Rem Mag has more energy at all ranges than the 30-06. At 500 yards, the 7mm Rem Mag has 1,735 foot-pounds (ft-lbs) of energy, while the 30-06 has 1,327 ft-lbs of energy with a 150-grain bullet.
Accuracy
Accuracy is important for making ethical shots and harvesting game quickly. Both cartridges are accurate, but the 7mm Rem Mag has less bullet drop and drift than the 30-06, making it more forgiving for long-range shots. The 30-06, on the other hand, has great stopping power and is more suitable for medium-range shots.
Conclusion
Both the 7mm Remington Magnum and the .30-06 Springfield have their strengths and weaknesses. If you are looking for a flat-shooting and high-energy cartridge for long-range shooting, the 7mm Rem Mag is a great choice. However, if you prefer a cartridge with great stopping power and accuracy for medium-range hunting, the 30-06 is a solid option. Ultimately, the choice depends on your personal preferences and the game you are hunting.
