Cartridge standards for the .375 Ruger were issued by SAAMI in June 2007. This force is nothing more than the acceleration of water away from the path of the bullet, hopefully leading to a wound channel larger than the bullet diameter. It was designed as a dangerous game cartridge, particularly for use in Alaska and Africa. As far as I know, these are the only production lever rifles offered in .375 Winchester and the .375 caliber versions are long discontinued, although Winchester still offers .375 factory . Read on for his take on this Thai-inspired fusion dish. They pulled up short, and, luckily, the bull they wanted turned and gave them a clear frontal shot. Of the heavy weight premium bullets the 300 grain Nosler is the softest. A person can end up with a very good rifle at fairly modest cost. bullets with express sights and hitting a 12"x12" steel gong at 100yds. For times when the brake is not preferred, it may be replaced with the included dynamically-matched muzzle weight. Made to work in Ruger actions, which couldn't fit full-length magnum cartridges. The .375 Ruger is a joint project between Hornady and Ruger, and it is the first big-game rifle cartridge to bear the Ruger name. The .375 H&H provides one of the world's greatest benchmarks for performance. A Vanguard in 375 H&H is listed on GB now for $1100: http://www.gunbroker.com/item/631076307 Last edited by a moderator: Mar 20, 2017 Hornady and Ruger partnered to create the cartridge. Thread Pattern: 5/8in-18. And much like the H&H case, the recoil of the .375 Ruger is easy enough for most shooters to handle; the cartridge generates right around 4,800 ft.-lbs. Such was my attitude in early June 2006 when Steve Hornady and I went to Zimbabwe. This was a walnut-stocked rifle, 23-inch barrel, good iron sights. I wasn't worried, but I was definitely concerned; if he didn't get him down on the spot, we would have a hard time finding him before morning. The case is of a rimless design having the base and rim diameter of .532in (13.5mm), which is the same diameter of the belt on belted magnum cases based on the .300 H&H Magnum and .375 H&H Magnum. The 375 H&H and 375 Ruger probably contributed somewhat to the sales decline of new Remy 375 RUMs. When hunting tough game weighing between 450 and 600kg (roughly 1000-1300lb) using a medium weight .375 bullet it really is hard to go past a homogenous copper bullet design utilized at close ranges as a means to increase hydraulic force. Finally, an opportunity came but cover was sparse, and we could only close the distance to about 100 . firemedic: While the 35 Whelen is adequate my Ruger Alaskan 416 Ruger is MORE "more than enough". At this time of writing there are now many buzz words used to label and describe bullets that are designed to enhance hydraulic action. From a muzzle velocity of 3000fps the TSX breaks 2600fps at around 115 yards, 2400fps at 180 yards and 2200fps at around 240 yards. Instead, Nosler developed a series of modest length rebated rim cartridges to suit the Howa action (Nosler M48 rifle). Much like a shortened version of the .375 RUM case design and similar to the .375 Dakota depending upon how one looks at it, Ruger, created a very potent .375 cartridge. This bullet is at its best when used on large bodied game such as bear or moose at closer ranges (above 2200fps or inside 250 yards depending on muzzle velocity). 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. Strong, simple, compact falling-block breech mechanism with artillery-style breechblock and under-lever is ideally suited for today's powerful cartridges. As a researcher, I tend to look for the poleax effect as this subject interests me as a matter of research. The .375 H&H, left, with the new .375 Ruger. This bullet differs quite simply in that it does not have any exposed lead at the bullet tip, similar to the Remington CoreLokt. The 270 grain Speer BTSP is a soft bullet designed for large thin-skinned game. The .375 Ruger cartridge and Ruger Hawkeye African bolt rifle are not flashes in the pan, but the author thought they could stand a little improvement. At Sportsman's Warehouse, we offer bolt action rifles chambered in .375 Ruger from leading manufacturers including Mossberg, Ruger, and Savage Arms. Depending on the year, conditions can be very dry as well. Shot the factory 300gr. Any human or rifle error will invariably result in slow killing. For more information on this subject please read The Practical Guide To Long Range Hunting Cartridges. But in cases where the design of the rifle simply produces intolerable recoil (as many do), one may simply have to lose 100fps or utilize a brake. Velocity is an additional key factor as this increases target resistance further. Yes, the .375 bore is forgiving, but it has its limits. Tips, techniques, and equipment are applied to these classroom discussions on how to become more proficient and successful at making long-range shots while hunting with AR-platform rifles. The WSM's and RCM's seem to have fallen behind. Ken and J.P. had already put on the brakes and put up the shooting sticks, so when the bull faced them Ken gave him a perfect frontal shot with a 270-grain Interlock. Although bullet construction is always the most important consideration for fast and clean killing. Only problem is that you are limited to only Hornady brass. Anything anybody needed in a .375-caliber cartridge was done in by Holland and Holland in 1912, right? Loaded to 3000fps the 250 grain Sierra (BC .371) breaks its 1800fps limit at around 520 yards. The .378 Weatherby, on the other hand, has never been popular because it is too much of a good thing: too much more recoil and too fast for most .375 bullets. Instead, I simply see them as being more useful on game weighing around or more than 450kg (1000lb) where angling shots are expected or where there is a chance of having to tackle animals of exceptional size for their species. Those who wish to body shoot heavy game with this bullet must understand that wounding will be limited. Those who want the highest possible velocities may wish to adopt a custom rifle start with a generous barrel length (my own preference is 26 to keep the blast and noise forwards while taming recoil). Is it significant that it fits in a .30-06-length action? It was early in the year when I heard the first rumor about a "new .375 cartridge." The .300 Ruger Compact Magnum or .300 RCM was designed in 2007 and uses a case designed by Hornady and Ruger based on the .375 Ruger cartridge. 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. I haven't shot the 260/270gr. The cartridge was designed in partnership, by Hornady and Ruger. It was designed to fit and function in the many "standard length" bolt-actions that work with cartridges like the 7mm Remington and .300/,338 Winchesters Magnums. With an Accu-Fit stock and left hand adjustable bolt, this rifle is a perfect choice for anyone! The case is of a rimless design having the base and rim diameter of .532in (13.5mm), which is the same diameter of the belt on belted magnum cases based on the .300 H&H Magnum and .375 H&H Magnum. The Woodleigh handles raking shots relatively well but is prone to lose a great deal of its sectional density if used to take Texas heart shots at close ranges. Most of the time a bull hit in this manner will take three or four steps forward to regain his balance, then he'll whirl and run the almost obligatory 50 or 60 yards of a buffalo hit perfectly in the chest. Currently, Hornady and Double Tap manufacture ammunition for the .375 Ruger cartridge. 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. Initially, the two Ruger M77 rifles designed for the .375 Ruger were the Hawkeye African and Hawkeye Alaskan. The Double Tap achieves 2,825ft/s (861m/s) and 4,700ftlb (6,400J) with a 270-grain Barnes TSX from a 23-inch barrel Ruger 77 African. Nosler, as an example, show loads yielding 2880fps with their 260 grain bullets but these velocities were taken in a 26 barrel. Three-position safety is easily accessible and allows the shooter to lock the bolt or to load and unload the rifle with the safety engaged. The .416 Ruger is a beltless, rimless, bottle-necked cartridge designed as a joint venture by Hornady and Ruger in 2008. Therefore to say that the Sierra can expand at 1600fps only relays a part of the picture, especially when its expansion is both limited and very much reliant on some degree of resistance (shoulder muscles and bone) in order to be at least partially effective. Unlike Winchester Short Magnum cartridges, the Ruger Compact Magnums share the same diameter from case head to body. From a muzzle velocity of 2950fps the Sierra kills with style out to ranges of around 170 yards (2200fps), thereafter producing clean but sometimes delayed kills out to 270 yards (1800fps). The 300 grain Nosler Partition is ideal for large Alaskan game out to ordinary hunting ranges. Nevertheless, this economical projectile design was acceptable for hunting game weighing up to 600kg (1300lb). The Hornady Superformance ammunition drives a 270-grain (17g) SP-RP bullet at 2,840ft/s (870m/s) and the 300-grain (19g) DGS and DGX bullets at 2,660ft/s (810m/s). This projectile is also too long to be housed in the Ruger M77. Additionally, the .375 Ruger yields around 6% greater case capacity than the .375 H&H. The full velocity increase can be had from a slightly shorter barrel--as in 22 or 23 inches--and a short 20-inch barrel at least equals and will generally exceed .375 H&H velocity. Between 2200 and 1800fps shot placement is the key on lean game. Regarding the solid bullet designs: these are most useful for CNS shooting. As Ruger intended the cartridge to be chambered in standard-length bolt-action rifles,[2] the case length was kept to 2.580in (65.5mm), which is only .04in (1.0mm) longer than the .270 Winchester case. Listed as discontinued. 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. 3 MOA over the bench and with a sled equates to around 6 MOA in the field if the hunter can keep his cool and more likely 9 MOA in real word conditions. Used on medium game at ordinary hunting ranges expansion on impact is extremely fast and exit wounds often very large, in the region of 3-4 in diameter. Barnes for example produce a 270 grain bullet but experience leads me to believe that this really only comes into its own on the heaviest of animals or in the most potent of .375 magnums. 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. The .375 Ruger (9.565.5mm) is a rimless, standard-length rifle cartridge designed for the hunting of large, dangerous game. To put either animal down on the spot requires both a tough bullet and careful shot placement. Those hunting the wilds of India, Australia, Canada and the United States all were well-served by the .375 H&H. This projectile is most useful where lower impact velocities are to be expected or where game weights are between 300 and 600kg (660 to 1300lb), though 600kg should be considered the upper limit. TDCC (Tables of Dimensions of Cartridges and Chambers) 300 PRC", ".300 PRC Review: Everything You Need to Know", "Hornady Ruger Compact Magnum Cartridge Review", C.I.P. Robust, sturdy, sculptured receiver forms a rigid support for barrel, stock and sliding breech block. The .375 Ruger was designed with the latest generation of powders in mind. It is potentially unwise to have a brake fitted to a short guide rifle to be used around clients. vs 9.3x62 Cartridge Clash, Kimber Hunter Pro Desolve Blak - A Lightweight Heavy Hitter, Browning BLR Lightweight '81 Stainless Takedown Lever Rifle, Mossberg Patriot Predator 6.5 PRC Rifle Review, Review: Springfield Armory M1A Loaded Rifle in 6.5 Creedmoor, RCBS ChargeMaster Lite Review: Not 'Lite' on Ability, Remington Model Seven SS HS Bolt-Action Rifle Review. The case measures .532 inches at the base and .515 inches at the shouldergiving a larger body diameter than the H&H designand is equipped with a 30-degree shoulder for positive headspacing. This change was made to prevent deformation of bullets under recoil. If this projectile is to be used for killing the meplat must be modified. This allowed Ruger to chamber the cartridge in their existing standard length M77 rifle, without needing to use their M77 Safari Magnum Rifle. Although no longer listed, a quick mention must go to the now discontinued 225 grain Hornady Interlock. Subscriber Services. By the same token, be wary of high weight retention projectiles that supposedly dump vast amounts of energy yet then defy physics by maintaining their form and weight. At 270 yards a 10mph cross wind send the Sierra flat point a full foot off course. Without due protection the Ruger brake can cause immediate hearing damage and a temporary loss of sight should gases blow back into ones eyes from the short barrel. This is due to the .375 H&H Magnum having a long, tapered body, while the .375 Ruger follows modern cartridge designs in that it has very little taper and a sharper shoulder. Heres how to avoid the poseurs and choose the right one. Doubtful given the 375 H&H in a standard length can be bought and does all that is needed of a .375. 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. I had been in Africa for some time before they arrived, and unfortunately, a left-hand version of the .375 Ruger couldn't be cobbled together before I departed. Hornady on the other hand, have placed some focus on smooth feeding. The 260 grain Nosler Accubond was designed for use on large bodied game. Mossberg & Sons produced bolt-action rifles of the "Patriot" series chambered in .375 Ruger with different stock options. The engineers at Hornady and Ruger teamed up in 2007 to produce a cartridge case with no parent; the .375 Ruger is a unique design. I have run .375 Ruger ammo through such actions and so far it has fed great every time. The left hand rifle options are also greatly appreciated. No worries--Wayne shot him very well, and the .375 Ruger literally threw him to the ground. I must say that Steve did some very good work with this rifle and cartridge. Readers are however advised to take note of the muzzle brakes on the current .375 Ruger rifles. A poorly selected .375 caliber bullet will always be vastly more forgiving than a poorly chosen .30 caliber bullet when facing the likes of Alaskan Brown bear. Mossberg & Sons", SAAMI Drawing 300 Precision Rifle Cartridge (300 PRC), "It's Official SAAMI Approves Hornady 6.5 PRC and 300 PRC", "C.I.P. The .375 Ruger cartridge case was used by Hornady as the basis for a new extra-long-range cartridge, since it had the capability to operate with high chamber pressures, which combined with a neck and barrel throat optimized for loading relatively long and heavy .308 diameter very-low-drag bullets without the need to seat the bullets deeply recessed into the case result in adequate muzzle velocities from magnum-sized bolt-action rifles. Feeding is superb, not only in the left-hand rifle but in all the right-hand rifles I have seen. OK, I was actually, grudgingly, impressed. Readers are advised to employ extra caution when using this bullet (and the heavier Accubond) in the .375 caliber on large bodied game or better still, avoid it altogether. 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. If using a lighter bullet we need to think about increasing retained weight after impact and using velocity to (hydraulic force) to promote trauma.
