300 Precision Rifle Cartridge (PRC) rounds are designed for big and long-range hunting purposes. The rounds pack a mean punch and are enough to handle heavy games from a long distance with ease.
These long, aerodynamic bullets came into the market in 2018 and have been widely accepted and praised for their remarkable firepower and precision at long range.
The .338 Lapua was invented in 1987 specifically for long-range shooting in the military. These high ballistic coefficient bullets have the ability to pierce through military-grade armor within 1000 yards.
300 Prc vs 338 Lapua: What’s the Difference?
The 300 PRC comes with a base diameter of 0.532” and its overall length is 3.7”. The bullets require a long bolt throw, and a magnum action rifle to reach their potential.
The manufacturer gave the bullets a long “head height”(1.12”) to achieve better aerodynamic projectiles and a high ballistic coefficient (BC).
.338 Lapua has a smaller overall length and larger bullet diameter. These powerful bullets pack a mean punch despite being smaller in size. They have a massive case capacity (114 gr) compared to the 300 PRC(77 gr).
The 300 PRC were designed for ELR precision rifle shooting and have an amazing trajectory.
For those who aren’t familiar, Trajectory is the bullet’s flight path as it travels downrange and this is measured in inches of bullet drop. The 300 PRC has a slightly flatter trajectory.
The trajectory of the .338 Lapua is slightly more curved and has a bit more bullet drop than the 300 PRC, meaning it will drop into the ground before the 300 PRC if shot side by side.
However, both cartridges are similar in terms of accuracy.
This is where the 300 PRC really shines. Even if the recoil changes depending on the weight of the rifle and bullet weight when you fire it at a specific muzzle velocity, the 300 PRC offers significantly less recoil (up to 70% less).
This might be true that the .338 packs a mean punch, but all that power comes at a price. The higher amount of recoil makes it difficult to use .338 for long-range shooting.
Using muzzle brakes may help solve the problem but the 300 PRC is the winner here, by a long shot (pun intended).
Accuracy is another tricky aspect to measure since it depends on factors like the rifle, barrel life, ammo consistency, the shooter’s skill, and environmental conditions.
Both the 300 PRC and the .338 Lapua are incredibly accurate within their effective shooting range.
However, the crown goes to the 300 PRC for high accuracy, long-range shooting.
The .338 Laupa falls behind in the competition due to its higher recoil and the 300 PRC’s flatter trajectory. The bullet is incredibly accurate but needs additional support to hit the bullseye if the distance is long.
Both the 300 PRC and the .338 Lapua cartridges can be reloaded with loads of your choice. Reloading might take a larger payment upfront from you, but this will reduce the cost up to 20-40% per bullet down the line.
The most common bullet weights for the 300 PRC are 212, 220, 225, and 250 grains.
Reloading gives you the freedom to create your own load specifically for your hunting/shooting purposes. The grains that are the most widely available for the .338 Lapua are the 250, 270, and 300 grains.
Sectional Density (SD) is the measurement of how much a bullet can penetrate a target. The measurement is calculated by comparing the bullet weight and the bullet diameter. The 300 PRC offers a higher SD than the .338 Lapua.
A bullet with a higher SD count will be able to penetrate its target better than its counterparts. The SD count of the .338 Lapua cartridges is a bit low so it won’t be able to go deeper than the 300 PRC and punch through thick hide, bone, and sinew.
Long-range target shooting isn’t cheap. With a smaller selection of bullet weights to choose from, the 300 PRC is a bit cheaper than the .338 Lapua.
There aren’t many long-range rifles available that can shoot the 300 PRC. You’ll have to spend around $6-7 for each round.
1. How far can I shoot a 300 PRC?
Ans. The 300 PRC is designed for ELR precision rifle shooting. You may have factory ammo calibrated for match shooting and still shoot out to 1,500 yards with this cartridge.
2. Which is bigger? 300 Win Mag or 300 PRC?
Ans. The cases for both 300 are similarly long but the PRC has a significantly longer cartridge. The 300 PRC is nearly a half-inch longer compared to the 300 Win.
3. Is 300 PRC a belted magnum?
Ans. The 300 PRC is based on the 375 Ruger cartridge case. This is a non-belted cartridge that uses headspaces off the 30-degree shoulder and the standard .532” magnum bolt face. The result is better chamber alignment and improved stacking and feeding from your fixed magazine.
4. Is there a semi auto 338 Lapua?
Ans. The Kivaari is a semi-automatic .338 Lapua mag rifle. This firearm weighs 13.6 pounds empty and operates on gas. The Kivaari provides quick follow-up shots which help in hunting.
5. What are the ballistics of a 338 Lapua?
Ans. The ballistics performance of 338 Lapua based off 5 different grain types:
|Grain Type||Ballistic Performance|
|300 gr Lapua Scenar||2,750 feet/second|
|300 gr Sierra HPBT||2,750 feet/second|
|250 gr Partition||2,940 feet/second|
|250 gr Lapua Scena||3,000 feet/second|
|200 gr||3,340 feet/second|
