Case destroyer
This tool is made of extremely low grade Austenitic stainless steels, it gets scored and gets marked very easily by brass in turn it accumulates brass and scores the inside of the cases even with RCBS case lube. This tool has cost me 300 new Lapua match brass. If you need a mandrel get one and take it to your local machine shop and have one made out of mild steel then ask them to temper it. Do not use the one made out of stainless steel, it will cause you huge headaches.

Not Up To The Task
Material far too soft for intended task. Despite the inside of the case necks being properly lubed, the mandrel 'loads' up with case material and galls succeeding case throats. Spend the extra money and purchase the carbide equivalents.
Wrong diameter
Sinclair customer since the early 90s and this is first time I've received a defective product. Ordered the 22cal expander and neck turning mandrels but both are exact same diameter as measured with two different calipers - .222". Painless return process including free shipping but am reluctant to order another for fear it may also be .001" too small. Product is well made, so was either finished to wrong diameter or marked and/or packaged incorrectly. Sad to say I'm sourcing a replacement expander from a competitor.
