Our neck turning tool mandrels are made from high grade stainless steel on Precision turning centers. The shape, finish, and size are the result of years of use and experimentation by many hand loaders. All of our mandrels fit both our NT-3000 and NT-1000 neck turning tools and most of our older model neck turning tools. Our neck turning tool mandrels measure approximately about .002"" less than the bullet diameter for the caliber. Our expander mandrels are made .001"" larger than the turning mandrels. Using an expander mandrel prior to neck turning sizes the case to fit the neck turning mandrels perfectly. This correct fit makes the turning process more precise and much easier. Any of the mandrels can be used to ""neck"" cases up to the next caliber when used with the NT-EXP (Expander Body).Delivery time approx. 7-14 days.
Introducing the Stainless Steel Expander Mandrels by Sinclair International, designed for the discerning hand loader seeking unparalleled accuracy and ease in neck turning.
Using an expander mandrel before neck turning sizes the case to fit the neck turning mandrels perfectly. This correct fit not only enhances the precision of the turning process but also makes it significantly easier.
Additionally, any of the mandrels can be utilized to "neck" cases up to the next caliber when paired with the NT-EXP (Expander Body), making this tool a versatile addition to your reloading setup.

Need for lube ! 30/08/2016
Works OK⦠if one complies w/ the ABSOLUTE need for lubing either the mandrel (?) or inside the case neck. Do consider groups WILL BE larger because 1) CBTO is not consistent and 2) not being consistent, pressures may increase due to change (.0.002±) brought about by neck tension variation(s) w/ NEW brass. In the end, 100 rounds fired to reach "perfection" of CBTO. So why use the Gen-II set up ?
