A Take a look at Cartridge Specs and Ballistics
The 7mm Remington Magnum Unveiled
The 7mm Remington Magnum, usually merely referred to as the 7mm Rem Magazine, holds a particular place in firearms historical past. Launched by Remington within the early nineteen-sixties, it shortly gained recognition. Based mostly on the basic .375 H&H Magnum case, the 7mm Rem Magazine was designed to supply shooters a considerably improved ballistics efficiency in comparison with different frequent seven-millimeter cartridges of the time. Its success was pushed by its efficient efficiency on a variety of sport and the benefit of which it might be loaded to go well with quite a lot of taking pictures pursuits.
The case itself gives an excellent steadiness of capability, effectivity, and total measurement. The 7mm Rem Magazine sometimes makes use of a variety of bullet weights, that are appropriate for various looking and goal taking pictures eventualities. Bullets from the one-hundred-and-forty-grain to the one-hundred-and-seventy-five-grain vary are generally employed, providing a steadiness between trajectory, sectional density, and retained vitality.
On the subject of velocity and vitality, the 7mm Rem Magazine demonstrates spectacular figures. As an example, when using a one-hundred-and-seventy-five-grain bullet, you may anticipate muzzle velocities across the two-thousand-eight-hundred-and-sixty ft per second mark, offering glorious downrange vitality. The drop at four-hundred yards may be comparatively average, making it simple to precisely estimate a shot.
Sectional density and ballistic coefficient play essential roles in a cartridge’s trajectory and vitality retention. Sectional density refers back to the ratio of a bullet’s weight to its cross-sectional space. Larger sectional density typically results in higher penetration and vitality retention. Ballistic coefficient, then again, is a measure of a bullet’s means to beat air resistance. A better ballistic coefficient interprets to a flatter trajectory and fewer wind drift. The 7mm Rem Magazine typically gives a really respectable ballistic coefficient with many standard bullet designs.
Exploring the 7mm Taking pictures Occasions Westerner
The 7mm STW, or Taking pictures Occasions Westerner, takes the already potent 7mm platform to the following stage. Initially conceived as a wildcat cartridge, it was created by Roy Weatherby and Layne Simpson, with the purpose of attaining even greater velocities and flatter trajectories than the 7mm Rem Magazine. Based mostly on the .375 H&H Magnum case necked all the way down to accommodate a seven-millimeter bullet. The STW possesses a notably bigger case capability than the 7mm Rem Magazine, which is a major consider its enhanced ballistic efficiency.
Designed to maximise ballistic potential, the STW gives a aggressive benefit. Once we have a look at bullet weights, much like the 7mm Rem Magazine, it might probably deal with a wide variety. However with the case capability benefit, it usually performs greatest with heavier bullets, able to being launched at unbelievable speeds.
The rate figures of the STW are actually spectacular. Using the identical one-hundred-and-seventy-five-grain bullet because the comparability, the 7mm STW can usually obtain muzzle velocities within the vary of three-thousand-and-twenty-five ft per second, and even greater, depending on the rifle and cargo. These greater speeds instantly translate to flatter trajectories, lowering bullet drop and growing the efficient vary. The vitality heading in the right direction at prolonged ranges may be substantial, providing a major benefit for long-range hunters.
The benefits in each sectional density and ballistic coefficient are very pronounced as effectively. The STW can propel heavier bullets to greater speeds, enhancing the ballistic coefficient and enabling them to retain extra vitality downrange in comparison with the 7mm Rem Magazine.
Evaluating the Numbers: A Ballistic Head-to-Head
To actually respect the variations, it is useful to have a look at the info side-by-side. For example this, let’s think about the efficiency of each cartridges utilizing a one-hundred-and-seventy-five-grain bullet, a preferred selection for each.
| Vary (Yards) | 7mm Rem Magazine Velocity (fps) | 7mm Rem Magazine Drop (inches) | 7mm Rem Magazine Power (ft-lbs) | 7mm STW Velocity (fps) | 7mm STW Drop (inches) | 7mm STW Power (ft-lbs) |
|—|—|—|—|—|—|—|
| Muzzle | 2860 | 0 | 3180 | 3025 | 0 | 3570 |
| 200 | 2550 | -2.5 | 2530 | 2740 | -1.8 | 2920 |
| 400 | 2260 | -17.8 | 1990 | 2470 | -10.3 | 2380 |
| 600 | 2010 | -51.1 | 1580 | 2220 | -31.9 | 1920 |
This straightforward illustration highlights the STW’s benefits, primarily by way of flatter trajectory and better retained vitality at longer ranges. Whereas the variations could seem refined at shorter distances, they change into considerably amplified because the vary will increase.
Efficiency Traits: The place They Excel

The 7mm STW, then again, can prolong the vary capabilities even additional. With its flatter trajectory and better retained vitality, the STW is well-suited for engagements at distances past 5 hundred yards. It will probably present higher efficiency than the 7mm Rem Magazine at very lengthy ranges, and is usually favored by hunters preferring pictures at these longer distances.
Searching Purposes: Matching the Sport
Each the 7mm Rem Magazine and the 7mm STW are exceptionally versatile cartridges for looking. They’re able to taking down all kinds of North American large sport species. The 7mm Rem Magazine is a stellar selection for elk, deer, and bear.
The 7mm STW gives the identical potential because the 7mm Rem Magazine however, once more, with the benefit of much more attain. The improved ballistics make it a wonderful possibility for bigger species, like elk and moose, and the potential of taking down these animals at prolonged ranges.
When deciding on the appropriate bullet, think about the sport, the vary, and the specified stage of enlargement and penetration. As an example, controlled-expansion bullets are sometimes chosen for elk and moose to make sure deep penetration.
Recoil: A Matter of Consolation and Accuracy
Recoil is a essential issue that may affect taking pictures consolation, accuracy, and follow-up pictures. The 7mm Rem Magazine, whereas providing substantial energy, typically has a manageable recoil. The recoil impulse is normally substantial however simple to deal with for a lot of shooters, permitting for fast follow-up pictures.
The 7mm STW, as a consequence of its greater velocities and bigger case capability, has a extra pronounced recoil. This may be uncomfortable for some shooters, and might have an effect on the time it takes for follow-up pictures. Whereas the 7mm STW does ship extra energy, the shooter’s means to precisely place pictures is essential.
