Nosler BST Bullets
1 Polymer Silvertip
Polymer Silvertip prevents deformation in the magazine.
2 Lubalox ®Exterior Coating
Reduces fouling, pressure and friction between bullet and bore; provides longer barrel life, easier cleaning and enhanced accuracy.
3 Fully Tapered Jacket and Special Lead-Alloy Core
Allows controlled expansion and optimum weight retention at all practical velocity levels. The heavy jacketed base prevents bullet deformation during firing.
4 Heavy Jacketed Base
Acts as a platform for large- diameter mushroom.
5 Ballistically Engineered Solid Base®
Boat tail configuration combines with the streamlined polymer tip for extreme long-range performance and for easier loading.
Lubalox® is the trade name Winchester uses to describe a black oxide process. It is a very thin oxide bullet coating, often compared to the bluing on a steel firearm.
The primary benefit of Lubalox is reduced barrel fouling. The process creates a surface on the bullet jacket, which increases the number of shots possible between cleanings. Unlike moly-coated bullets, Lubalox-coated bullets leave the barrel residue-free and do not require barrel “seasoning”. Additionally, unlike uncoated bullets that tarnish over time, Lubalox protects the surface of the bullet jacket, keeping it looking like new.
Lubalox does not harm the barrel. In fact, testing shows that the coating often reduces barrel fouling.
Lubalox® coating is not a Moly coating.
