SINCLAIR INTERNATIONAL
GENERATION II EXPANDER DIES

749008843

Description
Ratings (5)

Our Generation II Expander Dies completely capture the mandrel within the die so the mandrel cannot pull out. An O-ring in the die cap allows the mandrel to float a bit and find its own center within the case neck. All three Generation II dies are precision machined from stainless steel and the 7/8 inch - 14 dies include the Sinclair Stainless Steel Split Lock Ring. Large caliber expander dies accept only 35 to 50 caliber mandrels. All expander mandrels for Sinclair Expander Bodies are sold separately: Find Mandrels here.

Unbreakable and necessary for 6PPC (02/11/2011)

When forming 6PPC brass from LAPUA .220 Russian's you need this! Turn this on your loadin press, slip little imperial sizing die wax to .220 brass, small press with this and you have almost ready world most accudate 6PPC brass. Cheap, simple and unbreakable. With changeable mandrel you can use this very large scale of calibers. Rubbered O-ring beetween mandrel and die body allows small movements and it's more smoother for brass.

Sinclair expander Die. (09/08/2012)

I use this Expander Die with all my Reloading. I expand 270 WSM to 7MM for my long range rifle. It puts the right amount oftension on each bullet. It also smooths the inside of the case neck. Great Product. Very well made like all Sinclair products.

Very good product (20/05/2016)

Keeps necks straight with just the right amount of tension. Some expander balls leave brass with way too much neck tension not to mention the occasional neck pulled off center creating off center amo, Fliers. This is a simple well made tool and well worth the money.

Works great! (10/10/2016)

I purchased this expander die to improve neck uniformity with my .308 and .223 brass for target and competitions. The die is well made and easy to adjust. Under the cap is an o-ring which allows for some expander float. This helps the expander self-align and improves concentricity. I have used it with carbide and HSS expanders and recommend using lube for either. Imperial wax or a lanolin based spray work well.

Best of all it works with my PMA carbide and HSS expanding mandrels!

Why did I wait so long (16/07/2018)

Insert your desired arbor into the die and screw it into your press , while not over-tightening the cap to allow for a small amount of "float" for the arbor pin . I tried both Imperial Die Lube , and Imperial Dry Lube , and found the Dry Lube worked much better , and gave a smoother extraction of the arbor from the case . Since I shoot both F-Open , and F-TR , I go thru a lot of cases in a month , and this tool saves a lot of time , and improves concentricity to a standard of .0010-.0015 . Easy to set-up , easy to use , and worth every penny . Only wish I had purchased one three years ago . Nothing negative to say about this product . This tool , properly used will improve accuracy , Period !
