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.Coatings special features: No plastic burning smell Thermally stable Resistant to weathering and chemical degradation Strong mechanical and tensile strength properties Self-lubricating Able to withstand high pressure conditions Able to withstand high heat conditions High degree of wear and abrasion resistance Reduced friction resistance Good flame retarding properties Coating prevents lead to bore contact thus virtually eliminating lead fouling Shoot higher velocities without lead fouling
