Pacific Pistol Powder Measure.
If you don't want it, I'll take it.

I have the same blue powder measure by Pacific and all the discs that go with it. It is as accurate as any powder measure can be.
I bought a new HORNADY Pistol Powder Measure but, did not like their cut to accept a holder. I gave it to a friend who was badly in need of it.
