Best Uses
Good fit: range training, target shooting, and competition where a conventional 147 gr FMJ load is appropriate. The manufacturer lists this load as supersonic and non-expanding.
Not the right tool for: suppressed subsonic use, hunting where controlled expansion is required, or applications that call for a purpose-built defensive projectile.
Reliability Notes
No structured Ammo Reports submissions yet. Sellier & Bellot describes the load as providing reliable functioning and no barrel leading. Individual firearms, magazines, and barrel lengths can still affect function and velocity.
