Quick Answer
Nosler Partition bullets generally cycle well in most rifles, but their performance can be affected by factors such as chamber size, case headspace, and bullet seating depth.
Factors Affecting Partition Bullet Cycle
Nosler Partition bullets are known for their excellent expansion and penetration, but their cycling performance can be influenced by the rifle’s chamber size. A chamber that is too small can cause the bullet to become stuck, while a chamber that is too large can lead to excessive bullet movement and potential jamming. It’s essential to ensure the rifle’s chamber is properly sized for the bullet, with a minimum of 0.001 inches of headspace.
Seating Depth and Bullet Cycle
Proper bullet seating depth is also crucial for optimal cycling performance. A seated depth that is too shallow can cause the bullet to become loose, while a depth that is too deep can lead to excessive pressure and potential jamming. A general rule of thumb is to seat the bullet at 0.030-0.050 inches from the bullet’s ogive (the curved part of the bullet’s nose). This allows for sufficient clearance between the bullet and the rifling while maintaining proper alignment and stability.
Rifling and Bullet Cycle
The rifling of the barrel can also impact the cycling performance of the Partition bullet. A barrel with a sharp, well-defined rifling can help to stabilize the bullet and ensure proper alignment, while a barrel with a dull or irregular rifling can lead to excessive bullet movement and potential jamming. To ensure optimal rifling, it’s essential to inspect the barrel regularly and maintain it properly to prevent wear and tear. A rifling twist rate of 1:7 to 1:9 inches per turn is generally recommended for Partition bullets to maintain stability and ensure proper cycling.
