Has anyone tried imr4831 in this cartridge? I have some Barnes 127 grain bullets for it, but there isn't very much info out there for the 6.6 rpm. thanks

Barnes responds pretty quickly to email questions about loads.  :)

Man you’re right, I can’t find anything listed online for IMR4831. Seems like it would be close to the proper burn rate, though I use slower powders for my RPM.

Retumbo is the ticket in the 6.5 rpm.
