Recently bought a Yugo rebuilt K98 from the local "Big 5" sporting goods (non matching, excellent condition)and picked up some surplus 8mm ammo at a local gunshow. I don't recall but I think the ammo was either Yugo or Greek 1953 production military. The "Big 5" guns are supposed to be checked, headspaced and ready to go (except for some cosmoline cleaning) At the range the gun turned out to be an excellent shooter (1.5" groups @ 100yds) however every 4th or 5th round the bolt was very hard to open and when I did get it open I found the primer blown out of it's seat. As I said only some rounds did this others would eject fine. A blown primer would certainly indicate high pressure of some sort.
So... is this excessive headspace? Bad ammo? or something else im not thinking of?
Any input would be appreciated.
