Arisaka headspace issues?
TLDR: non matching rifle does weird stuff with brass, considering a chamber cast or finding a headspace gauge.
I have a rifle that came with a broken off bolt handle, I got a new bolt body and everything seemed to work fine after swapping parts over (cycling, dry fire, safety, etc).
But at the range I was met with two light strikes (See photo #2, also the unfired round on the right). I pulled that one out and tried a different round which went off first try, but the case expanded and locked the bolt up bad enough to where I needed a mallet; i believe this may be how the previous bolt was broken. Looking at the brass I'm worried about the chamber being deformed. Any advice is appreciated! (Edit: shell in the middle is for reference, it is the same norma ammo just fired from a friend's type 99)
