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.

You will get poor performance and a lot of soot going too low.
Stick with at least the min load of 5.6 or even a bit more. Believe it or not the Berrys Plated are not a whole lot different than FMJ in semi autos. When I used them, I used exactly half of the min/max FMJ data. Which in this case is almost 6.0 grs (5.95grs)
