Lock ring size Change?

Hello Dillon,

Recently I bought tools from Dillon to begin reusing my 25 year old 550, One thing I bought that did not work was the Dillon wrench. Has Dillon decreased the size of the die lock rings, from the 550 to 550b? If so, is there by any chance a older wrench i could trade this one in for?

Thanks Eric

The lock rings were reduced from 1 1/8" to 1" diameter about seven years ago. This was done to create more room to swing the wrench.
