Looking for some good load data for the 400 corbon. I'm interested in good target loads and not to push to the max. I've been hearing you can use 10mm data. Honestly, I think starting at the min with the slower powders like 231 to unique maybe the best? suggestions?

Take this with a grain of salt, as they are not pressure tested.

FYI: Unique powder is a medium burn rate.
W231 is faster then that.

BTW: I don't think 10mm data has much to do with a necked down .45 ACP.
A major differance in case strength and pressure between the two.

.400 Corbon pressure = 26,500 to 29,000 psi
10mm pressure = 37,500 PSI.

Back when I was fooling around with .400 Cor-Bon, I found AA#7 to be a great powder. AA#5 works o.k., too. Load data is available on Cor-Bon's website. Be careful about setbacks, particularly if you're trying to get the .400 Cor-Bon to feed from a staggered magazine. I loaded over 10,000 .400 Cor-Bons until I "discovered" 10mm. Wish I'd made that discovery a lot $ooner. ;)
