Precision-ground stainless steel mandrel set for .224 caliber reloading. Four interchangeable mandrels provide .0005" neck-tension increments from .0005" to .0025" when combined with your ZERO sizing die.
Area 419's Mandrel Sizing Kit represents a thoughtful approach to one of reloading's most critical variables: consistent neck tension. This kit contains four precision-ground mandrels that work in concert with Area 419's ZERO M-Series or S-Series sizing dies.
Consistent neck tension is fundamental to ammunition uniformity. By offering four mandrels with precise .0005" increments, this kit lets you find the exact neck tension that works best for your specific rifle and shooting application. Whether you're loading for precision rifle competition or hunting, the ability to fine-tune this variable can measurably improve your results.
This is a tool for reloaders who understand that precision ammunition begins with precision equipment.
