What happens when you cross a .308 Win with a 300 WSM? You get the 300 PRC. It’s a cartridge that offers the best of both worlds, giving you the punch and trajectory of the .308 Winchester and the power and speed of a 300-grain bullet at 2,650 feet per second.

This can make it an excellent choice for hunting large game like deer or boar where long-range shots are required but penetration is needed as well. Whether you choose to hunt with it or not, there’s no denying how cool this cartridge is! But what if I told you there was another round just like it? It would be heavier by only one grain (300 RUM). And while they both share many similarities—including their popularity among hunters—they also have some differences. Which one should you choose?

300 PRC VS 300 RUM

If you are a fan of hunting big game with a rifle, then this article might be of interest to you. In this article, we will look at the popular 300 PRC vs 300 RUM cartridges and see which is better for hunting purposes.

First off: what are the differences between 300 PRC and 300 RUM?

300 PRC is a short-action cartridge based on the 6.5 Creedmoor case design with no neck dimensions or shoulder angles changed from that cartridge. The length of this cartridge was designed so it could fit into any rifle with a short action (i.e., less than 1 inch). Usually, these rifles have an overall length of 39 inches or less when equipped with iron sights and mounts included (with scope attached).

Some bolt actions may require removal of some material from their forends due to how long they can be; however most rifles will be fine as long as they were designed around the standard barrel lengths available today (around 24-26 inches). This means that most deer hunters can find rifles chambered in .308 Winchester / 7 mm-08 Remington / 7 mm STW / .260 Remington etc… that will work well with these cartridges without having to modify anything themselves!

What is a PRC?

PRC stands for Precision Rifle Cartridge, a designation that tells you a lot about what this cartridge is designed to do. The PRC was designed by Tony Rumore, who had previously designed the .260 Remington and .300 Remington Short Action Ultra Mag cartridges. The purpose of the 300 PRC was to be an accurate long range hunting cartridge that would work in short action rifles like the Remington 700 and Winchester Model 70.

The 300 PRC uses a 9mm diameter case necked down to accept 7/8″ (.311″) bullets instead of 5/8″ (.308″) bullets found in most other .30 caliber cartridges including the .308 Winchester and 7mm-08 Remington. By using smaller calibers and lighter bullets, shooters can achieve greater velocity at longer ranges than they could with larger calibers or heavier bullets without sacrificing bullet energy at those ranges.

What is a RUM?

The Remington Ultra Magnum (RUM) is a rifle cartridge that was developed in the 1960s. It was designed for use in big game hunting and can be found on rifles like the Remington 700 and 783, among others.

The RUM uses .284 inch diameter bullets and has an overall length of 2.850 inches. The bullet weighs 180 grains, which makes it heavier than most other rounds at the same size.

This makes it ideal for larger species such as elk or moose since it delivers more kinetic energy when fired at those animals compared to other types of ammunition with less mass and velocity; however, these attributes also make it unsafe for small game like deer thanks to their lack of protection from impact forces—even though they’re still considered legal under current laws pertaining solely to firearm cartridges rather than meat consumption regulations themselves!

You should choose between these two types based on how much money you want spend investing into practice sessions before going out into nature itself.”

Is a PRC or RUM a good choice for hunting?

At the end of the day, both are excellent rifles. If you are looking for a rifle to hunt game and want something that is still powerful, then a PRC might be your best bet. However, if you are looking for a rifle that can fire at long distances and hit targets with precision, then the RUM should be on your list of considerations.

The PRC has better accuracy than its counterpart due to its heavier weight (it weighs more than twice as much) and slightly longer barrel length (the RUM’s barrel is only 1 inch longer).

The RUM is more powerful than the PRC because it uses higher pressure cartridges which provide greater velocity and knock down power against larger game. This means that it will take down bigger animals like deer or bears quicker than an equivalent caliber cartridge loaded in a PRC would do so.

Which cartridge is better?

The PRC is a bit more affordable than the RUM, but you should definitely consider your budget before making a decision. The PRC will suit hunters who want to take down their prey quickly and efficiently, while the RUM is best suited for target shooters and those who enjoy precision shooting.

If you’re on a tight budget and have no desire to hunt or shoot at long distances, then we’d recommend picking up some 300 PRCs instead of 300 Rums (which are pricier). However, if money isn’t an issue, then by all means go with the 300 RUM!


It’s clear from the data above that the 300 PRC is a better choice for hunting than the 300 RUM. It has more energy, so it’s able to put down bigger game more effectively. The 300 PRC also offers a flatter trajectory and increased accuracy, making it easier to hit longer shots.

If you’re looking for an excellent cartridge in .300 Norma Magnum caliber with top-notch ballistics and performance, but want something that’s still very affordable compared to other similar calibers like 338 Winchester Magnum or 338 Lapua Magnum—or even other short-action cartridges such as 7mm Remington Short Action Ultra Magnum or 6mm Creedmoor—then this cartridge may be right up your alley!
