Underwood Ammos hard cast featuring a new Black Cherry coating. Equipped with new enhancements from the previous Hi-Tek coating. The 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. Hard cast flat nose bullets are non-expanding, powerfully penetrative bullets that are designed with wood defense needs in mind; whether fending off wild hogs or black bears, the hard cast flat nose bullets are consistently effective in taking down any wild animals that you may encounter.
