Define "nuclear hot." Are you saying it's impossible to be over pressure without overt signs?

I'd love to see someone run quickload on this, what was your barrel length again?


For giggles...and yes I know it's quickload and there are limitations based on inputs. 22-in barrel, 2.8"OAL 7-08 Rem with 120 TTSX and 120 NOS BT.
