Quick Answer
For 7mm SAUM reloading information, consult the Hodgdon Varget reloading manual, the Sierra Bullets 7mm SAUM reloading manual, or the Hornady 7mm SAUM reloading manual for accurate and reliable data.
Choosing the Right Reloading Manual
When selecting a reloading manual for 7mm SAUM, consider the level of detail and the sources of data. Hodgdon’s Varget manual offers a comprehensive set of loads for various 7mm SAUM cartridges, including a 140-grain Hornady SP load with a maximum charge of 83.5 grains of Varget. Sierra Bullets’ manual provides a range of loads using their various bullet styles, including the 150-grain MatchKing.
Understanding SAAMI Pressure Limits
To ensure safe and reliable reloading, it’s essential to stay within SAAMI (Sporting Arms and Ammunition Manufacturers’ Institute) pressure limits. For the 7mm SAUM cartridge, the SAAMI maximum pressure is 65,000 psi. When choosing a reloading manual, look for loads that meet or exceed this pressure limit to ensure the cartridge will function reliably in the field. For example, the Hornady manual lists a 150-grain Interlock load with a maximum charge of 81 grains of H4831sc, which meets the SAAMI pressure limit.
Applying Reloading Data to the Field
In the field, it’s essential to apply the reloading data with caution. This means carefully following the manual’s instructions, using the correct components, and monitoring the load’s performance in a controlled environment before taking it to the field. For elk hunting, a safe minimum load is essential to ensure a clean and humane kill. For example, a 150-grain 7mm SAUM load at 2,800 fps will typically provide a deep penetration and a wide wound channel, making it suitable for large game like elk.
