STAINLESS STEEL EXPANDER MANDRELS

STAINLESS STEEL EXPANDER MANDRELS Reviews & Ratings

SINCLAIR STAINLESS STEEL EXPANDER MANDRELS

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).

Expander mandrel
Adding the 6.5 caliber expander to my reloading bench. Have used these mandrels for years. Take the expander out of my full length dies and use the Sinclair expanders for almost perfect concentricity.

Sinclair expander die
I wish I could tell you how the mandrels work, I’ve been waiting for for the Sinclair expander die body #749011715 to be available for two months. I’ve left a request to be notified when it’s available twice, the first time you replied that it was available but when I tried to purchase it, the website still said it was unavailable. I’m still waiting.

30 Cal Expander
This 30 caliber expander appears to have worked exactly as designed. Prior to expanding my new ADG 300 WSM cases, I experienced multiple cases essentially crush/ mushroom at the neck while pressing the bullets into the case even after full-length resizing the case. After expanding the case neck on several cases, the bullets pressed in perfectly & I’ve not had any more mushroomed cases.

Perfect
This one is as good as the others I have purchased and used. If you don’t have a specific caliber buy all the mandrels anyway. One day you will have the caliber.
