Back Up/Expander for 300 blackout

Hi,

I've setup a separate 1050 toolhead for 300 blackout and I've temporally borrowed the backup expander from the  223. Considering the neck is now for 30 cal, should we have a .308 backup expander instead of a 223 to achieve proper belling?


Back Up/Expander .308/30-30 12074


Regards,

Iroquois
