Are there accuracy differences between factory and handloads for 7mm Rem?

Understanding the Accuracy Gap

The accuracy difference between factory and handloads in 7mm Remington Magnum is largely dependent on the quality of the factory ammunition and the expertise of the handloader. Factory ammunition can be accurate, but it may not reach its full potential due to manufacturing tolerances and quality control issues. On the other hand, handloaded ammunition allows for precise control over powder charges and bullet seating, enabling shooters to optimize their loads for specific rifles and hunting conditions.

Load Development and Optimization

To achieve optimal accuracy, handloaders should focus on developing loads that are tailored to their specific rifles and ammunition. This involves experimenting with different powder charges, bullet types, and seating depths to identify the combination that produces the smallest group sizes. A good starting point for 7mm Remington Magnum handloads is to use a moderate to fast burning powder, such as H1000 or RL22, and a bullet weight between 140 and 160 grains. For example, a load with 90 grains of H1000 and a 150-grain ballistic tip bullet has been known to produce groups as small as 0.5 inches at 100 yards.

Real-World Accuracy Expectations

In the field, accuracy expectations for 7mm Remington Magnum handloads can vary depending on the individual’s skill level, rifle condition, and environmental conditions. However, with proper load development and optimization, it’s not uncommon for experienced shooters to achieve consistent 1-2 MOA accuracy at 100 yards. For elk hunting, this level of accuracy is more than sufficient for placing a shot on a large animal at moderate ranges.
