Neck Expanding Mandrel - Stainless Steel
Our Neck Expanding Mandrels are designed to fit both the 21st Century Shooting and Sinclair Expander Dies. Our mandrels are longer than other expanding mandrels and feature a special dual taper which expands both on the up and down stroke of the press to more uniformly expand and straighten case necks.
Expanding Mandrels are available in the following calibers:
17, 20, 22, 6mm, 25, 6.5mm, 270, 7mm, 30 and 338
These mandrels are perfectly matched to suit our turning mandrels, they are sized to allow for the spring back in the brass and to maintain a snug fit on the turning mandrell, allowing consistent neck tension and uniformity during the turning process.
Also available in our Neck-Up mandrels for 22cal – 6mm and 6mm – 30cal. Perfect for necking 220 Russian up to 6mm for PPC and 6BR up to 30 caliber for 30BR.
If you are doing a lot of turning and why not check out our carbide turning mandrels - they maintain dimensional accuracy over a wide temperature range.
Our mandrels are marked as follows, the numbers represent the calibre:
17 = .177
22 = .224
24 = .243 ( 6mm)
25 = .257

27 = .270
28 = .284 (7mm)
30 = .308 (7.62mm)
33 = .338
N30 - N = Neck turning, 30 is calibre, so an N30 is a Neck Turning 30 Calibre
X26 - X = Expanding, 26 is calibre, so an X26, is an expanding .264 (or 6.5mm)
X24X - is a special Neck-Up mandrels to go from 22cal to 6mm in one step, Perfect for necking 220 Russian up to 6mm for PPC
