Although it has since spawned the .416 Ruger and the shortened Ruger Compact Magnums (RCMs), it started as an original case design that used the .532-inch rim but without a belt, the case is fatter with little body taper and a 60-degree shoulder. The combination of full bullet expansion plus around 30% weight loss help the 300 grain partition to produce massive internal wounding across a wide range of impact velocities. The key here is to put aside notions of extremely fast kills. To start with, a person hunting in areas that are "off range" during . 2023 Outdoor Sportsman Group. They do produce a bit more recoil. Those who wish to hunt light framed game at bush / woods ranges or in semi open country, where shots are not long, may wish to consider using the 200 Grain Sierra flat point bullet (BC .200) designed for the .375 Winchester. Additionally, the .375 Ruger yields around 6% greater case capacity than the .375 H&H. That said, hand loaders must be careful not to make general assumptions based on any published data as there is a great deal of variation in bullet shape and jacket thickness in the medium bores, especially with regards to premium bullets. Forerunners to the .375 Ruger are the .376 Steyr and the .375 Dakota. These bullets work well when facing game weighing 700kg (1540lb) and above. The Barnes bullets do not suffer over-expansion. The Woodleigh is a fast killer of light framed game at bush / woods ranges but is somewhat underutilized in this role. This is one of the great virtues of the medium bores and why it is such a shame when hunters label them as being suitable for big game only. The Weldcore bullet really comes into its own when the going gets tough, an emphatic killer of large and tough bodied deer and Antelope when used out to ordinary hunting ranges. While not earth shattering on its own, the wide and compact case is more efficient than the Holland & Holland which enables the Ruger to obtain similar results from a short 20 barrel while a 23 barreled Ruger boasts higher velocities than a 25 barreled H&H. The new cartridge uses the same .532-inch rim diameter, but the belt is fatter and the body taper has slightly more case capacity even though, at 2 1/2 inches, it'. Between 2400 and 2200fps the TSX produces clean but delayed kills. It is designed to provide an increase in performance over the .375 H&H cartridge, yet to be chambered in a standard-length action rifle. Apart from this the Sierra has great merit. The 375 H&H and 375 Ruger probably contributed somewhat to the sales decline of new Remy 375 RUMs. With a 95-year track record, it is also a benchmark for bullet performance. Hornady 's new Superformance loads produce a bit more velocity, and the rifle refinements made by Hill Country Rifle make it more accurate and user-friendly. As a researcher, I tend to look for the poleax effect as this subject interests me as a matter of research. Wounding is severe however if used in this manner. This allows the cartridge to have a greater case capacity than a belted magnum case given cases of equal length. Apart from this small change, the RP Interlock performs the same as the traditional bullet. Personally, I don't give much of a hoot about the extra velocity. But there are some animals which are just so large and tough that unless we were to use a Chey-Tac, or perhaps a .50 BMG, there is simply no way they are going to go straight down with ordinary body shots and there is no point chasing maximum velocities. The maximum overall length of the cartridge is 3.340in (84.8mm), which is similar to the maximum overall length to standard-length cartridges such as the .338 Winchester Magnum or the .30-06 Springfield.

Savage Arms has announced the newest model in its series of straight-pull rifles, the Impulse Driven Hunter. Of the heavy weight premium bullets the 300 grain Nosler is the softest.

The efficiency of the cartridge actually yields a dual bonus. It is potentially unwise to have a brake fitted to a short guide rifle to be used around clients. It is both forgiving and can be more humane than the small bores in bush hunting situations as poor shots taken with the .375 generally slow game down fast, allowing quick follow up shots. Based purely on case capacity, a fairly straight .532-inch-diameter case with a fairly sharp shoulder should do this, and it does. There are a few easy modifications to improve the feeding reliability. Robust, sturdy, sculptured receiver forms a rigid support for barrel, stock and sliding breech block.

While expansion may still be fully evident at 2200fps, hunters targeting heavy game would do well to consider 2400fps as a wise cut off point for wide wounding. Do the iron sights hit poi with 260/270gr.bullets ? As Ken had promised, when I got home there was a long Ruger box awaiting me, and in it was the very first left-hand Ruger M77 in .375 Ruger.

Those who wish to experiment with it for hunting will need to utilize either a custom action with a generous length magazine box or be prepared to single feed loads into the M77 action. Once again, there should be no surprise in what a cartridge that slightly exceeds a .375 H&H should do on game, provided the bullets perform. Similar to the design ideas for the WSM cartridge family, but somewhat narrower which will frequently allow one more cartridge in the rifle magazine than the WSM equivalent. Like the .376 Steyr that originates from the 9.364mm Brenneke and the .375 Dakota proprietary cartridge that originates from the .404 Jeffery, the .375 Ruger was designed to compete with the .375 H&H Magnum, yet have the advantage of having a rimless, beltless case and can function through a standard-length bolt-action rifle due to a shorter overall length. The cartridge is a bit "snappier" than the 375 H&H and I believe can achieve about 200 fps more velocity if fired from the same length barrels.
