Exploring Different Performance Parameters

Several factors contribute to the performance of a cartridge. Let’s take a look at the PRC and RUM variants of the .300 category!

1. Overall Trajectory During Shooting Sessions

A flat trajectory ensures that the round will hit its target without dropping down less. This allows the shooter to hit their target accurately at long distances. Both calibers offer unmatched performance in this category.

Overall Trajectory During Shooting Sessions

Lighter bullets cannot travel great distances due to having less inertia while heavier bullets can go a long distance and hit the target with accuracy if fired by a skilled shooter.

  • Accuracy is affected by a longer range but at an ideal distance, the RUM offers impressive velocity and flatter trajectory.
  • The PRC variant does not hurt the barrel life energy level (factory loads) and the bullet coefficient is exceptional.

Winner: The 300 PRC takes the lead here and is declared a winner in this category.

2. The Energy

When dealing with different animal games, the projectile’s energy plays a critical role in putting them down at a long distance.

  • A RUM is known for its stopping power but the same can not be said about its possessed energy.
  • With the PRC variant, you are firing high-bullet coefficient rounds having more energy. This makes them ideal for long-range situations experienced by target shooters.
The Energy

Winner: The 300 PRC wins here for its energy and reliability in various hunting and target shooting scenarios!

3. Long-Range Precision Shooting and Accuracy of the Rounds

The .300 PRC offers:

  • Higher accuracy and is specifically designed for hitting targets with maximum reliability.
  • The powder burn of this precision rifle cartridge, perfect bullet seating, and lower sway of bullets are an advantage to hitting the target with maximum precision.
  • The combination of precision and high BC bullets is lethal to hit a target at a great distance with pinpoint perfection.
Long-Range Precision Shooting and Accuracy of the Rounds

The 300 RUM cannot be underestimated for accuracy but the larger size inflicts wear and tear reducing the life of the barrel.

  • This ultimately results in difficulty hitting the target.
  • Also, the large amount of pressure that this cartridge imposes on the barrel results in heating and inconsistent variations between each shot.

Winner: 300 PRC wins this category with flying colors!

4. Recoil Rate Experienced While Shooting the Two Cartridges

Recoil rate is a major factor when you are firing this round with long-range potential.

  • An increased amount of powder in the cartridge and muzzle velocity results in more recoil while shooting the 300 RUM. The, PRC performs better in terms of recoil rate.
  • Additional factors that contribute to the recoil are the type and size of a rifle being used, the bulk of the firearm, and accessories (muzzle brake).
Recoil Rate Experienced While Shooting the Two Cartridges

Winner: The 300 PRC is excellent for target shooting due to a less recoil rate!

5. Long-Range Shooters and Applicability for Various Situations

The 300 PRC (Precision Rifle Cartridge) and 300 Remington Ultra Magnum) are versatile and have the potential for various hunting and target practice scenarios. The .300 PRC is unmatched during long-range competitions as it ensures precision and trustworthy performance.

Long-Range Shooters and Applicability for Various Situations

In hunting, both cartridges excel to deliver reliable performance:

  • The 300 RUM has a higher muzzle velocity (2920) and more energy (3975) resulting in stronger recoil.
  • Shooting a 300 PRC round feels a little less recoil (2810 muzzle velocity) making it suitable for beginners and extremely long-range shots.

Winner: The PRC wins! It is highly accurate and target shooters who like to be at a distance always prefer it!

6. Power

If more power is needed then the RUM is the best choice during big game hunting. The .300 RUM is capable of taking down large targets without much problem. Although, you have to be habitual of the heavy recoil of the firearm after a shot. But, being compatible with small, medium, and big game makes it a preferred choice by most hunters.


There is a difference between stopping power and energy:

  • The PRC may be faster and excellent on long-range.
  • The RUM packs a stronger impact on contact making it more lethal in distances under 500 yards.

The only downside is added strain on the barrel which many custom barrel makers are tackling.

Winner: The RUM is a powerhouse and it can take down larger targets effortlessly!

How Far Will a 300 RUM and 300 PRC Shoot?

As we have highlighted the long-range capabilities of the cartridges above. The precision of the ammo is affected by various factors such as:

  • The barrel length of the gun
  • Shooting conditions
  • Bullet choice (grain, weight, and shape of bullet)
  • Skill level (beginner or pro-level hunter)

What is the difference between a 300 RUM & 300 PRC?

The difference between a 300 RUM vs 300 PRC is that the RUM is designed for practical use during big games such as deer hunting, mule deer, elk, moose, etc. In comparison, the PRC is the only cartridge used for long-range shooting.

What is the advantage of a 300 PRC?

The advantage of a .300 PRC over other calibers is that it has a high ballistic coefficient. Therefore, it travels faster.

What’s the difference between a 300 PRC and a 230 Grberger?

The main difference between a 300 PRC and a 230 Geberger is the 15 fps.

Is the 300 RUM better than the 300 PRC?

If you like shooting long-range and prefer extremely flat trajectories then the 300 RUM is your pick. But, for people who love the accuracy and high-speed rounds that can travel a large distance, the PRC is an excellent choice.

Is the 300 RUM good for long-range shooting?

The 300 RUM for long-range shooting is effective if you want a hunting cartridge to take down a body weight of 400kg (880 lbs) or less. It is perfect for most big games during your hunting situations.


Shooters with different preferences select the round depending on the type of target, hunting situation, and stopping power needed. If you like long-range hunting then you will like the 300 PRC and 300 RUM depending on the felt recoil and the ability of the cartridge to hit hard on the target.

If you usually hunt big game then the RUM is your top pick but if smaller targets and precision is needed then go for the PRC. Both rounds can hit with accuracy but the PRC is better in terms of precision. While RUM is ideal if a larger prey needs to be quickly taken down as it offers exceptional stopping power.
