Quick Answer
Reloading 7mm SAUM can enhance accuracy over factory loads by allowing for precise control over powder charge, bullet selection, and seating depth, which can result in a tighter group size.
Customizing the 7mm SAUM
When reloading the 7mm SAUM, it’s essential to start with a reputable case, such as the Remington 7mm SAUM case or a custom case from a reputable manufacturer. This will ensure a consistent case volume and internal dimensions, which are critical for achieving accuracy. A good starting point for the powder charge is 60-65 grains of a high-performance powder like H4350 or Retumbo, which can produce velocities in excess of 3,000 feet per second.
Optimal Bullet Selection
Selecting the right bullet for the 7mm SAUM is crucial for achieving accuracy. A good starting point is a 140-150 grain bullet with a high ballistic coefficient (BC) like the Berger VLD or the Hornady ELD-X. These bullets offer excellent expansion and penetration, making them ideal for elk hunting. It’s also essential to choose a bullet with a suitable ogive and boattail design to minimize wind drift and maintain a stable trajectory.
Precision Seating and Loading
To achieve the best possible accuracy, it’s essential to use a precision seating die and a high-quality bullet seater. This ensures that the bullet is seated to the correct depth and is properly aligned within the case. A good starting point for the seating depth is around 0.020-0.030 inches above the case shoulder, which will provide the optimal amount of engagement with the rifling.
