Speer 4410 Bull .400 165 TMJFn 100

Overview

40/10mm TMJ - Total Metal Jacket Diameter: .400 Weight: 165 Ballistic Coefficient: 0.135 Box Count: 100 Uni-Cor Construction Uni-Cor-a simple name for a complex and revolutionary process for building jacketed handgun bullets. Speer developed the techniques for electro-chemically building a bullet jacket one molecule at a time. The result? It produces a truly bonded-core bullet allowing Speer to offer features not available from other bullet makers. Most handgun bullet failures are caused by core-jacket separations. Think about it. If the core and jacket start as separate pieces aren t they more likely to end up in pieces after expansion? With Uni-Cor one core is made and then the jacket is built on to it. The result is a tough stable bullet with incredible jacket concentricity. Note: These are component bullets not loaded ammunition.
