Official-data note: A verified exact-load factory ballistic table was not available during this review. Estimated values have been removed.
Key takeaway: The verified product identity is a 145 gr bimetal-jacket FMJ load with a polymer-coated steel case and Berdan primer.

Steel-Cased Construction and Magnetic Bullet Considerations
Wolf Polyformance ammunition uses a polymer-coated steel case rather than brass. The coating serves as a lubricant substitute to ease extraction in semi-automatic chambers. The bullet itself is bimetal — a lead core with a copper-washed steel jacket — which means it will attract a magnet. This is a critical distinction for range use: many indoor ranges in the United States prohibit bimetal or steel-jacketed projectiles due to fire risk from sparks against steel backstops. Before use, confirm the range’s current policy on magnetic or steel-jacketed projectiles and check the rules that apply in the relevant jurisdiction. This review does not make a legal classification; Wolf describes the projectile as a bimetal-jacket FMJ.
Best Uses
Good fit:
- High-volume range training where per-round cost is the primary driver
- Outdoor range sessions where steel-jacketed bullets are permitted
- Carbine drills, position shooting, and 300 Blackout platform function testing
- Competitors running large round counts in practice and needing an affordable supersonic load
- Shooters breaking in a new 300 BLK upper and wanting to confirm cycling before switching to premium ammunition
Not the right tool for:
- Indoor ranges with steel-backstop facilities that prohibit magnetic projectiles
- Hunting applications that call for a controlled-expansion bullet; verify the applicable regulations before use
- Suppressed shooting where subsonic 300 Blackout performance is the objective (this is a supersonic load)
- Precision or long-range work where published BC data and verified velocity are required
- Shooters whose rifles have match chambers with tight tolerances that may not feed steel-cased ammunition reliably
Reliability Notes
No structured submissions yet.
From manufacturer claims and open sources, not structured data: Wolf describes this load as designed for consistent performance in semi-automatic platforms. The polymer coating on the steel case is intended to reduce friction during feeding and extraction compared to bare steel, which historically caused more wear concerns. Open-source user observations suggest that gas-impingement AR-platform rifles in 300 Blackout generally cycle this ammunition without issue, though some users note that rifles with very tight chambers or aggressive extractor springs may experience occasional extraction stiffness — a characteristic common to steel-cased ammunition across all calibers, not specific to this load. Bolt-action users report no extraction difficulties. No recall or safety notice is associated with this product at time of publication.

FAQ
Is this brass-cased?
No. Wolf identifies a polymer-coated steel case.
Is the primer Boxer or Berdan?
It uses a Berdan primer.
What does Wolf state about reloadability?
Reloadable status was not found in verified official material. Wolf does list a polymer-coated steel case and Berdan primer.
Why are there no ballistic numbers?
An exact-load manufacturer table could not be verified, so estimates were removed.
Can the bullet attract a magnet?
Yes. A bimetal jacket can attract a magnet.
