New for 2019! Our expander mandrels are available in .0005” increments in calibers 22 to 338 and will range from .001” above bullet diameter to at least .003” below bullet diameter depending on caliber. This will allow the reloader to find proper neck tension to fine-tune their loads. The oversized expanders will also help straighten necks prior to sizing to improve concentricity. Extra steps are involved in the machining of these to ensure precision and they are double checked prior to packaging.
No return on these Expander Mandrels - All are specified diameter
