Do expanding bullets perform better for deer with 7mm Rem Mag?

Ballistic Performance Comparison

The 7mm Remington Magnum is a versatile cartridge capable of delivering high kinetic energy to the target. For deer hunting, expanding bullets are often preferred over non-expanding bullets due to their ability to create larger wound channels, increasing the chances of a quick kill. The 7mm Remington Magnum can push a 140-grain expanding bullet to velocities over 3,000 feet per second, resulting in a kinetic energy transfer of approximately 2,200 foot-pounds. In comparison, a non-expanding bullet may not expand as significantly upon impact, potentially leading to a longer, more painful death for the deer.

Bullet Selection Criteria

When selecting an expanding bullet for deer hunting with the 7mm Remington Magnum, it’s essential to consider the bullet’s weight, velocity, and expansion characteristics. A bullet weighing between 140 and 160 grains is commonly recommended for this cartridge, as it provides an optimal balance of kinetic energy and expansion. The bullet’s expansion ratio, measured by the percentage of expansion, should be around 1.5 to 2 times the original diameter. Examples of suitable expanding bullets for the 7mm Remington Magnum include the Barnes TSX, Hornady InterLock, and Nosler Partition.

Hunting Techniques and Recommendations

To maximize the effectiveness of expanding bullets in the 7mm Remington Magnum, hunters should focus on making clean, precise shots at the target. Aiming for the deer’s vitals, such as the heart or lungs, ensures a quick and humane kill. In addition, hunters should consider using a scoped rifle with a sufficient magnification power, such as 3-9x or 4-12x, to ensure accurate shots at longer ranges. Furthermore, practicing regular shooting sessions and familiarizing oneself with the rifle and bullet combination is crucial for achieving consistent results in the field.
