The .375 Ruger: An Up And Coming Dangerous Game Cartridge?

Keep reading to learn all about the .375 Ruger cartridge.

The venerable .375 H&H Magnum has been the most popular dangerous game cartridge in the world for over 100 years. During its long reign, there have been many cartridges developed and marketed as competitors to the legendary .375 that just didn’t quite measure up and eventually fell by the wayside. The .375 Ruger is the latest contender for the crown and just might succeed where the others have failed. Why is this the case? Though there are many things to like about the .375 Ruger, the major selling point of this fantastic cartridge is that it’s the first cartridge to deliver performance comparable to the .375 H&H from a standard length (instead of a magnum length) case. Continue reading to learn all about the .375 Ruger and why it is such a unique cartridge.



Developed in a joint venture between Ruger and Hornady, the .375 Ruger was first introduced to the shooting public in 2007. The idea was to create a cartridge similar in length to the .30-06 Springfield, but with a case capacity comparable to the .375 H&H. By using a straight, unbelted case with a non-rebated .532″ rim, they were able to accomplish their goal. In fact, they were able to exceed expectations because the slightly fatter and non-tapered 65.53mm (p133) .375 Ruger case actually has approximately 5% more case capacity than the 72.39mm case (p131) used by the .375 H&H.

.375 Ruger compared to a .375 H&H

For this reason, the .375 Ruger compares very favorably to the .375 H&H and both cartridges perform at an almost identical level ballistically. Like the .375 H&H, the .375 Ruger is accurate, powerful enough to quickly and ethically kill virtually any species of big game, and has a manageable amount of recoil that most shooters can handle. Considering the reputation of the .375 H&H, this is high praise indeed.

In fact, most .375 Ruger loads actually slightly exceed the velocities delivered by standard .375 H&H loads when shooting the same weight bullet. However, this velocity edge is small enough that it doesn’t make much of a difference in reality. The .375 H&H is already a capable cartridge at extended range and while the .375 Ruger is a marginal improvement, the difference in trajectory between the cartridges is small. At the same time, the extra velocity doesn’t make it much better at killing game, and I doubt any animal can tell the difference between a bullet fired at 2,700fps vs 2,800fps.

However, this sight velocity advantage can allow rifles chambered in .375 Ruger to use shorter barrels and still have ballistics that are nearly the same as the .375 H&H. When you combine this with the fact that the .375 Ruger fits in a shorter action, it allows hunters to use rifles that are shorter, lighter, and handier than comparable rifles chambered in .375 H&H.

The shorter length of the .375 Ruger case is the primary selling point of the cartridge and, since the cartridge basically mirrors the .375 H&H in performance, the shorter case is a significant advantage. Instead of being restricted to using only the larger, more expensive magnum length action rifles, the .375 Ruger opens up a whole line of great quality, commercially successful, standard length action rifles that may be adapted for the cartridge and repurposed for dangerous game.

.375 Ruger Loads

At this time, Hornady and DoubleTap are the only two manufacturers that produce factory loaded .375 Ruger ammunition.

Hornady loads their 250gr GMX, 270gr SP-RP, and 300gr DGX/DGS bullets to advertised velocities of 2,900fps, 2,840fps, and 2,660fps respectively (using a 24″ barrel).  DoubleTap currently offers loads with 260gr Nosler Accubond along with 235gr and 270gr Barnes TSX bullets with advertised loads of 2,900fps, 3,100fps, and 2,825fps respectively (using a 23″ barrel).

Even though there aren’t many choices out there when it comes to factory ammunition, the good news for hand-loaders is that the .375 Ruger can be reloaded using just about any of the vast number of different .375 bullets on the market originally designed for the .375 H&H. For instance, hand-loaders have bullets like the Barnes Triple Shock, Nosler Partition, and the Hornady DGS/DGX (just to name a few) to choose from. The other good news is that it is possible for hand-loaders to safely duplicate factory ammo performance of the cartridge using commercially available powders.

The .375 Ruger is also a pretty accurate round, particularly when used in a good quality rifle. Even though it was not designed as such, it is still a capable extended range cartridge in the right hands. Especially when using lightweight bullets, a 250-350 yard shot (perhaps even further) is well within the capabilities of the cartridge. That being said, most hunters utilize the cartridge in such a way that the vast majority of their shots are taken at ranges less than 150 and often less than 100 yards. Under these conditions, the .375 Ruger excels and the fact that the rifles it is typically used in are often shorter and faster pointing really becomes an asset.

The .375 Ruger unquestionably produces more recoil than both the .375 H&H and the 9.3x62mm Mauser. However, the recoil, while stout, is still manageable for most hunters.

Hunting With The .375 Ruger

Like the .375 H&H, the .375 Ruger is an incredibly versatile cartridge. With factory loads that produce well in excess of 4,500 foot pounds of energy, the cartridge meets the legal requirements to hunt members of the African Big 5 and other species of dangerous game in virtually every country in the world. It is absolutely deadly on a wide range of animals varying in size from whitetail deer all the way up to elephant. The heavier 270gr and 300gr loads are particularly versatile and are well suited both for larger game like buffalo, brown bear, grizzly bear, moose, and eland as well as small/medium sized game like impala, wildebeest, deer, feral hogs, and black bear. Heck, the .375 Ruger shoots flat enough that it’s even suitable for longer range shots, like those you’re likely to encounter while mountain goat or caribou hunting as well.

The cartridge also shoots flat enough that it is possible to confidently take shots out to 250 yards or so without adjusting the point of aim. As you can see in the videos below, it still packs quite a punch at 200+ yards.

As the saying goes, the proof is in the pudding and more and more hunters are starting to realize what a fantastic cartridge the .375 Ruger is. The cartridge, particularly when used in the handy Ruger Guide Gun with its 20″ barrel, is starting to develop quite a following among guides and professional hunters in Africa and Alaska who want a powerful, fast pointing rifle to use at close range on angry dangerous game, like bear and buffalo. It cannot hold a candle to the .375 H&H in terms of popularity or availability of ammunition, especially in remote locations, but the .375 Ruger is catching up fast and ammunition is much more common than it was even a few years ago. Indeed, it is arguably one of the best rifles for hunting Africa.

The .375 Ruger is a great cartridge, but I don’t see it supplanting the .375 H&H as the most popular dangerous game cartridge anytime soon. Even though it has a number of advantages over the .375 H&H on paper, performance in the real world is not the same as performance on paper. The cartridge is certainly coming along and developing a growing following. However, the .375 H&H has been around for more than a century and has a stellar reputation among hunters. It is going to take many years of great performance before people feel the same way about the .375 Ruger (if they ever do).

Is the .375 H&H dead? Not by a long shot. Do you need to dump your .375 H&H and get a .375 Ruger? Not necessarily. That being said, if you’re looking for a single cartridge to hunt the widest variety of big game possible, then a good rifle chambered in .375 Ruger just might be the right choice for you.

    Law of physics would seem to dictate that the recoil from a 375 Ruger is virtually the same as that sustained from a 375 H&H, yes? However, if it is being used more widely in the shorter barreled rifles (e.g., M77 Hawkeye Guide Gun), which presumably are lighter than standard 375 H&H rifles, then is it logical to say the 375 Ruger tends to produce more recoil? I only have a 375 H&H (CZ) and never shot a 375 Ruger, though I’d like to.
