6.5-300 Weatherby Magnum Ammo: In Depth
The 6.5-300 Weatherby Magnum is a high-performance rifle cartridge introduced by Weatherby in 2016. It combines the popular 6.5mm (.264) bullet diameter with the large case capacity of the .300 Weatherby Magnum, resulting in a cartridge that offers exceptional velocity, flat trajectory, and long-range performance. This round is designed for long-range hunting and competitive shooting, pushing the boundaries of what's possible with a 6.5mm bullet.
Development and Characteristics
The 6.5-300 Weatherby Magnum was developed to meet the growing demand for long-range hunting and shooting cartridges. It utilizes the .300 Weatherby Magnum case necked down to accept 6.5mm bullets, resulting in a cartridge that can propel these efficient projectiles at velocities exceeding 3,500 fps.
This cartridge is known for its exceptional ballistic coefficient, which allows it to maintain energy and resist wind drift at extreme ranges. The combination of high velocity and aerodynamic 6.5mm bullets results in a very flat trajectory, making it easier for shooters to make accurate shots at varying distances without significant holdover adjustments.
While the 6.5-300 Weatherby Magnum offers impressive performance, it does come with some trade-offs. The high velocities and large powder charge result in significant recoil and muzzle blast. Additionally, the intense pressures and velocities can lead to accelerated barrel wear compared to more moderate cartridges.
Applications and Usage
The 6.5-300 Weatherby Magnum excels in long-range hunting scenarios, particularly for medium to large game. Its high velocity and energy retention make it effective on animals like elk, moose, and large deer species at distances beyond the practical range of many other cartridges. The flat trajectory also simplifies shot placement at varying ranges.
In competitive shooting, particularly in long-range disciplines, the 6.5-300 Weatherby Magnum has gained a following. Its ability to deliver high velocities with relatively low recoil (compared to larger magnum cartridges) makes it a viable option for shooters looking to maximize their effective range while still maintaining manageable recoil.

Sectional Density Comparison
Sectional density is a measure of a bullet's mass relative to its diameter. Higher sectional density generally indicates better penetration and energy retention.
| Cartridge | Bullet Weight (gr) | Sectional Density |
|---|---|---|
| 6.5-300 Weatherby Magnum | 130 | 0.266 |
| 6.5-300 Weatherby Magnum | 140 | 0.287 |
| 6.5-300 Weatherby Magnum | 150 | 0.307 |
| 6.5-300 Weatherby Magnum | 160 | 0.328 |
| 6.5-300 Weatherby Magnum | 180 | 0.369 |
Note: Sectional density is calculated as (bullet weight in pounds) / (bullet diameter in inches)². Higher sectional density generally indicates better penetration, but other factors like velocity and bullet construction also play significant roles in overall performance. The 6.5-300 Weatherby Magnum offers excellent sectional density values, contributing to its reputation for long-range performance and penetration.
