Underwood Ammo’s hard cast featuring a new “Black Cherry” coating. Equipped with new enhancements from our previous Hi-Tek coating. Our “Black Cherry” coating is a polymer-based compound; its thermal stability allows it to handle more than any other coating today. The coating will protect against gas cutting with a high degree of wear and abrasion resistance. The “Black Cherry” coating prevents lead to bore contact thus virtually eliminating lead fouling. All 10mm firearms can safely function with this upgraded projectile. To include polygonal rifling (Glock).
