21st Century Caliber Specific Black Nitride Expander Mandrel Kit - 25 cal

Our Caliber Specific Expander Mandrels are now available in Black Nitride!  Black Nitride adds a degree of hardness and friction reduction to the surface of the mandrel.  This helps minimize galling that can occur.   

Our Black Nitride Caliber Specific Expander Mandrels are available in .0005” increments in calibers 22 to 338 and are available in seven sizes per caliber from -.003" below to caliber diameter.  Incremental mandrels will allow the reloader to find proper neck tension to fine-tune their loads. We recommend our Moly Dry Neck Lube for use with all of our expander mandrels.

The set includes seven expander mandrels. 
Machined to hold a tolerance of  +/_  0.0002" 
Please use Micrometer to measure.
