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.
