I ordered some match 308 ammo from southwest ammo awhile back and it took a bit longer than expected to get it shipped. To make up for this error they included a box of 147gr fmj NATO. While checking it out I attempted to chamber a round of the NATO stuff and found that the bolt was fairly difficult to close, tried another round and had similar results. One round even was difficult to extract unfired. I didn't shoot any of it yet but I am wondering if it would be a bad idea to use this in my gun just for plinking. The gun is a savage 10 that has only seen match factory ammo or hand loads.
