The 300 Win Mags perceived recoil is about 30 percent more powerful than a 30-06s, which is already substantial. At 30 ft lbs, the 300 Win Mags recoil energy places it on the upper threshold of what shooters can tolerate for any reasonable amount of time. It is roughly comparable to firing a 12 Gauge slug. Allowing a greater mid-range trajectory might result in shooting over an animal at an intermediate distance. Web300 Win Mag 178 gr ELD-X Precision Hunter . According to QuickLoad, the case capacities of .300 Win Mag brass produced by four ammunition manufacturers measure as follows: With heavier bullets boasting high sectional density and ballistic coefficients the cartridge possesses the long range performance necessary to take large game species at extended ranges. Prior to the advent of the .300 Winchester Magnum there were already a number of .30 caliber (7.62mm) cartridges billed as offering a magnum level of performance.

By adding trajectories to the panel on the right you may produce charts and graphs that show the different trajectories side by side. Bullets weighing 9.710.7g (150165gr) are adequate for smaller deer such as the mule deer and white-tailed deer. Beginning with the .270 Weatherby Magnum in 1943, Roy Weatherby introduced a popular line of rifle cartridges based on the H&H case shortened to fit a standard length (2.5in[63.50mm]) action. Factory loads are usually loaded to leave the muzzle at 3,250 feet per second, offering the hunter a very flat bullet suitable for long range shots.

Many hunters have found the cartridge to be an effective all-around choice with bullet options ranging from the flatter shooting 150 grain to the harder-hitting 200+ grain selections available in factory ammunition.

The SAAMI specification .300 Winchester Magnum case capacity is 91.5 grains of H2O (5.93 ml). The 165 grain bullet provides a higher ballistic coefficient than similarly shaped 150 grain bullet while maintaining a very high velocity which is translated into a flatter trajectory. Of course, the actual distance the bullet should hit above the point of aim at 100 yards (or 100 meters, which is about 108 yards) varies with the individual caliber and load. As a testament to its accuracy, following its introduction, it went on to win several 1,000-yard (910m) competitions.[5]. Due to its worldwide ability and ballistic capability to shoot flat and carry its energy efficiently, due to its high sectional densities and ballistic coefficients, the cartridge is one of the more favored rounds for African plains game as well as big game hunting for different species and hunting conditions globally. The .300 Winchester Magnum was designed with a neck which is shorter than the diameter of its bullet. Versatility Both of these calibers are excellent hunting cartridges that have been used to take any game in North America.

In the table below I used the term "mid-range trajectory," abbreviated "MRT.". It is particularly useful when hunting the members of the ungulate family such as sheep, deer, elk, and moose; being popular cartridge among hunters for these class 3 game species. Coaching volleyball is one of my biggest passions. [34] However, by the time Winchester got around to designing their own .300, the .308 Norma Magnum and the .30-338 were already on the scene. This 56-inch kudu bull fell to a 180-grain Trophy Bonded Tip bullet while hunting with Kowas This system maximizes the distance in which no "hold over" is necessary. This 300 Win Short Mag shows 180 grain Federal Premium Power Shok Copper Hollow Point Rounds. As a rough comparison, the recoil of the .300 Winchester Magnum is roughly comparable to a 12 gauge shotgun shooting 1 oz. However, the handloader can take advantage of modern advances in powder technology and actually exceed the velocity of the MK 248 MOD 1 cartridge while still loading to maximum SAAMI cartridge overall length, and maintaining safe pressure. WebHome Ballistics Charts Ultra-high velocity, magnum ammunition is how Roy Weatherby got started in the 1940s. This trajectory table can also serve as a comparative tool, allowing the reader to compare the trajectories of different cartridges or loads. Capable of stabilizing bullets weights ranging from 110 to 220 grains, the .300 Winchester Magnum happens to be a very versatile cartridge for different purposes and conditions including big game hunting, bench rest shooting and military applications. WebThe trajectories in the table below were calculated for a maximum bullet rise of 1.5 inches above the line of sight for all small game and varmint loads, and three inches above the line of sight for all big game loads. Elk can weigh as much as 450 kilograms (1,000lb) and moose 640 kilograms (1,400lb). Generally speaking, the higher the muzzle energy, the higher the stopping power. This can be useful in comparing cartridges or loads. [17][18], "So, while the .300 Winchester Magnum does very well with standard .30-caliber hunting bullets from 150 to 180 grains, it starts to lose ground with extra-heavy bullets of 200 grains and more"[17], With its velocity, low bullet drop and high energy retention, the .300 Winchester Magnum is useful for hunting sheep and other mountain game species, even at extended range, which may be considered unethical for many sport hunters. The down side to this performance is recoil. Use this ballistic calculator in order to calculate the flight path of a bullet given the shooting parameters that meet your conditions. The amount of recoil the cartridge generates is a step up from the non-magnum .30 caliber (7.62mm) cartridges. The .30 Newton saw limited commercial success, however, and the .300 H&H was too long for the standard length Mauser and Springfield rifle actions of the time, barring substantial modifications. regulated countries are currently (2013) proof tested at 537.50MPa (77,958psi) PE piezo pressure.[11]. Due to the short neck, heavier bullets particularly those weighing greater than 13 grams (200gr) and mono-metal bullets such as the Barnes X bullets will need to be seated more deeply into the cartridge. If Winchester had released the cartridge prior to 1960, the cartridge would have been similar to the .30-338 Winchester wildcat cartridge. The decision for which round is better for a given application should be made with complete information, and this article simply serves as a comparative guide, not the final say. Many consider the .300 Winchester Magnum to be on the lighter side of what is required for the largest bears, but loaded with heavier bullets, hunters have had success with the cartridge against these large bears.[22].

Red Oak, White, or Chestnut for Deer Herd? Military and law enforcement departments adopted the cartridge for long-range use, particularly by snipers. Used as such it can save a lot of trial and error experimentation. Furthermore, the muzzle energy of a .270 Winchester round averages out to2700 ft-lb, while a .300 Winchester Magnum round averages out to about 3520 ft-lb. Maximum effective range is generally accepted to be 1,210 yards (1,110m) with ammunition incorporating low-drag projectiles. Usually a 165 grain bullet shot from a .300 Win Mag has a muzzle velocity of approximately 3160 fps, which is 100 to 150 fps slower than the lighter 150 grain bullet. Hornady Our next 300 WSM ballistics chart shows 165 grain InterLock American Whitetail rounds. This was the first time the Pentagon's Director, Operational Test and Evaluation (DOT&E) tested the round, which can hit targets out to 1,200m (1,312yd). On the other hand, recoil is subjective (some are more sensitive to it than others) and one can get used to it with practice.
