This round was developed with a projectile that is soft enough to expand upon impact, but hard enough not to create lead fouling in the barrel of a normal revolver.Underwood Ammo's soft 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 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 resistance...
