Silver Bear Ammo in a GSR
My son picked up a box of Silver Bear .308 steel cased ammo as we were heading out to the range. It was the only .308 the LGS had on hand. When he fired his GRS he commented on how tough the bolt was to open. Since it's a pretty new rifle, I urged him to try some of my reloads, but he decided to go ahead and fire the mag.
On the second round he said it seemed a bit easier, but the third round did not want to unlock at all. After a bit of tugging on the handle, the bolt striped off of the case, leaving it in the chamber. We took a cleaning rod and knocked the case out and after not seeing any damage we fired my .308 reloads without issue.
First I wanted to warn others about this stuff and I wonder if he might have done any harm long term.
We put 30-40 rounds through it that day and like I said, no problems, but I've never had that happen before. I also refuse to use steel cased ammo in my guns. He had always poked fun at me being old fashioned about this point of view until this happened.
