Description
The 300BLK Selous Machined Expander Projectiles are solid copper 30 caliber projectiles designed to expand at subsonic velocities above 750FPS. It was designed using state-of-the-art ballistics modeling software to maximize stability at subsonic velocities. The projectile requires 1:8 twist or faster 300BLK barrel properly stabilize.
Quantity: 40 projectiles
Weight: 188gr
Length: 1.378″
BC: .404G1
Minimum Expansion Velocity: 750FPS
Note: The Selous projectile feeds best with 300BLK specific feed ramps. M4-style (narrow) feed ramps may need to be polished/widened for optimized feeding of the Selous bullet – Here is a video on how to do that.
