Underwood Ammo's hard cast featuring a new "Black Cherry" coating. Equipped with new enhancements from their previous Hi-Tek coating. Their "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 smellThermally stableResistant to weathering and chemical degradationStrong mechanical and tensile strength propertiesSelf-lubricatingAble to withstand high pressure conditionsAble to withstand high heat conditionsHigh degree of wear and abrasion resistanceReduced friction resistanceGood flame retarding propertiesCoating prevents lead to bore contact thus virtually eliminating lead foulingShoot higher velocities without lead fouling Hard c...
