I have recently picked up an old sportered Israeli Mauser from my brother in law, its a Czech K98, in German style with the handguard ahead of the rear sight. Im planning to do as close to a full restore as i can once i have the money. It was converted to 308 sometime in the past and when loaded seems to operate fine till you get to the last round in the mag. When the bolt comes back the number 4 round ejects and the fifth pops out of the mag and fall on the ground, iv taken the rifle apart, cleaned it up, and inspected it for anything obvious to my untrained eye. Does anyone have any ideas what might cause this, and how to fix it, id like to solve it myself before going to a smith if i can. Thanks for any help.
