Interesting problem here. EDIT - wow, after seeing your latest picture it definitely blew the shoulder out! But the case bulged in the weak area immediately ahead of the case head, leading one to believe there is no support for the case walls. I.E. the chamber diameter is MUCH larger than 0.473. The -03 is a CRF action, correct? Has the bolt face been opened up for a larger diameter?
