Arisaka fired cartridges and bolt face pics

Here's a picture of the blown primers followed by a picture of the bolt face. It looks to me like the two pits in the bolt face correspond to the blown primer. On the right hand cartridge it looks (to MY eye) like there are actually two places blown, which would correspond to the two pits on the bolt face. If memory serves me, that is also the cartridge that had a heavier load of powder and hence higher pressure.
