Based on a bunch of sources:
Zero brand 158 gr JHP
range brass
13.8 gr. Alliant 2400
1.575" OAL
tight enough crimp
I loaded up 100 of these, half with CCI 500 SP primers, half with CCI 550 SP magnum primers
I got about 1,050 fps out of a 4" Security six, about 1,100 fps out of a 6" 686+, right in line with the published data.
But they're smoky and leave shmutz everywhere.
I'm pretty sure the crimp is plenty strong, 'cuz when I disassembled one with an inertial de-bulleter I had to hit hard enough to slightly separate the lead core from the jacket.
The max load is 14.8 gr according to Speer and Alliant. Am I likely to see cleaner/more complete burning as I move up from 13.8 to 14.8? (I've seen max loads for 2400 as high as 15.5 elsewhere on the 'net)
