In terms 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 possibly can count on muzzle velocities across the two-thousand-eight-hundred-and-sixty toes per second mark, offering wonderful downrange vitality. The drop at four-hundred yards could be comparatively reasonable, making it straightforward 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 usually results in higher penetration and vitality retention. Ballistic coefficient, then again, is a measure of a bullet’s capability to beat air resistance. A better ballistic coefficient interprets to a flatter trajectory and fewer wind drift. The 7mm Rem Magazine usually provides a really respectable ballistic coefficient with many well-liked bullet designs.
Exploring the 7mm Capturing Occasions Westerner
The 7mm STW, or Capturing Occasions Westerner, takes the already potent 7mm platform to the following degree.

Designed to maximise ballistic potential, the STW provides a aggressive benefit. Once we take a look at bullet weights, much like the 7mm Rem Magazine, it may deal with a wide range. However with the case capability benefit, it usually performs greatest with heavier bullets, able to being launched at unimaginable speeds.
The speed 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 toes per second, and even greater, depending on the rifle and cargo. These greater speeds immediately translate to flatter trajectories, decreasing bullet drop and rising the efficient vary. The vitality on course at prolonged ranges could be substantial, providing a big benefit for long-range hunters.
The benefits in each sectional density and ballistic coefficient are very pronounced as nicely. 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 admire the variations, it is useful to take a look at the info side-by-side. As an instance this, let’s think about the efficiency of each cartridges utilizing a one-hundred-and-seventy-five-grain bullet, a well-liked selection for each.
