The Lee 9mm factory crimp die is a popular choice among reloaders, known for its affordability and effectiveness in creating a reliable crimp on 9mm Luger cartridges. But what makes this die stand out, and is it the right choice for your reloading needs? This comprehensive guide delves into the specifics of the Lee 9mm factory crimp die, exploring its features, benefits, and potential drawbacks. We'll also provide tips and tricks to ensure you achieve consistent, high-quality crimps every time.
Understanding the Lee Factory Crimp Die
Lee Precision's factory crimp die is designed to apply a roll crimp to the case mouth, securing the bullet and ensuring reliable feeding and function in semi-automatic pistols. Unlike a taper crimp, which gradually reduces the case mouth diameter, a roll crimp uses a precisely controlled rolling action to create a uniform crimp. This type of crimp is generally preferred for 9mm Luger ammunition because it's less likely to damage the bullet or cause feeding problems.
