Have you guys noticed...
That this thread is almost 4 years old, until today??? The OP surely has his problem solved long ago.
A universal depriming die is exactly that--a die that deprimes any case. That's all it does, BTW, unlike a full-length or neck sizing die, which deprimes in addition to resizing. Sometimes there is a need to ONLY deprime, and some reloaders like to separate the 2 operations.
Any pair of work gloves will protect the hands when removing live primers. It is also recommended to wear ear and eye protection.
But, hey, guys, this has all been covered before. Why do we need to re-hash it?
