Thanks everyone for the info. Looks like a Speer#14 manual might be a good addition to my reloading bench. Am absolutely amazed at 5.5 gr. Unique for 9mm luger. Was half expecting to see numbers in the 3's, just didn't think the case would hold that much--definately won't be an issue with double charging. Will start with a small batch loaded at 5.5 gr. of Unique. I measured WWB 9mm fmj's I am using currently for crimp & OAL. Believe the crimp was .375 & the OAL was 1.161-1.164, which work fine in my 5906. So am planning on setting seating/crimp die to those specs.
