With regards to velocity and vitality, the 7mm Rem Magazine demonstrates spectacular figures. For example, when using a one-hundred-and-seventy-five-grain bullet, you’ll be able to count on muzzle velocities across the two-thousand-eight-hundred-and-sixty ft per second mark, offering wonderful downrange vitality. The drop at four-hundred yards will 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. Increased sectional density typically results in higher penetration and vitality retention. Ballistic coefficient, then again, is a measure of a bullet’s potential to beat air resistance. The next ballistic coefficient interprets to a flatter trajectory and fewer wind drift. The 7mm Rem Magazine typically gives a really respectable ballistic coefficient with many widespread bullet designs.
Exploring the 7mm Capturing Instances Westerner
The 7mm STW, or Capturing Instances Westerner, takes the already potent 7mm platform to the following degree.

Designed to maximise ballistic potential, the STW gives a aggressive benefit. After 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 finest with heavier bullets, able to being launched at unimaginable speeds.
The speed figures of the STW are really 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 larger, depending on the rifle and cargo. These larger speeds instantly translate to flatter trajectories, decreasing bullet drop and growing the efficient vary. The vitality heading in the right direction at prolonged ranges will 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 larger 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 really admire the variations, it is useful to have a look at the information side-by-side. As an instance this, let’s contemplate the efficiency of each cartridges utilizing a one-hundred-and-seventy-five-grain bullet, a well-liked 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) |
