Quick Answer
Reloads can perform as well as, and often better than, premium factory ammo, but it requires precise control over variables like powder charge, case trim, and bullet seating.
Understanding the Variables
When comparing reloads to factory ammo, it’s essential to consider the variables that affect performance. A 0.1-grain difference in powder charge can result in a 5-10 fps difference in muzzle velocity. Similarly, a 0.01-inch difference in case trim can affect bullet seating depth and potentially lead to inconsistent accuracy.
Case Preparation and Seating
To achieve consistent results, it’s crucial to prepare cases correctly. This involves deburring internal and external surfaces, cleaning the chamber, and trimming cases to precise specifications. When seating bullets, a consistent depth is critical; a 0.01-inch variation can affect point of impact. A good rule of thumb is to use a micrometer to measure bullet seating depth and a depth increment of 0.001 inch.
Powder Charge and Bullet Selection
Selecting the right powder charge and bullet combination is also crucial. A 1-grain difference in powder charge can result in a 20-30 fps difference in muzzle velocity. When selecting bullets, consider factors like weight, profile, and BC to ensure optimal performance. For example, a 160-grain bullet with a BC of 0.5 may be more suitable for longer-range hunting than a 150-grain bullet with a BC of 0.4.
