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.
