20SCC Reloading Info Quest

[Bonemaker]

Anyone out there working up loads for this cartridge?
I am getting one built and looking for a starting point and any tips that may be had.

You have the dies? They're custom dies. These guys make 'em and will very likely have data.
Add the W's. .customreloadingtools.com/crt_087.htm
You may want to rummage here too, but there isn't much. .smallcaliberclub.com/

Thanks Sunray - the Small Calibre Club is a wealth of info as they were the ones that developed the cartridge. Have the dies on order so just waiting for the toy to be finished.
Will be very interesting to see how it actually performs.

Hoping to hear from someone that is up and running with a 20SCC.
