Good day all,
I blew a primer today and need assistance in determining what happened
Rifle: Savage 10 FCP in 308, all stock except a new trigger. it has approx. 150 total rounds though it in the past 6 months.
Load date
.308 Win Lapua brass, fired once before in the same rifle. This load was neck sized only.
168 gr TSMK
44.0 gr IMR 4064
Win primers
2.800" COAL
Velocity is mild - 2640 FPS average
I had put 20 rounds though the rifle today over the course of about an hour and it was shooting well. However the temp was over 90 degrees and the barrel was heating up fairly fast. It was definitely on the warm side when I chambered the round that blew.
The round that blew the primer chambered fine with no difference between it and previous rounds. I noticed no difference when firing either, and the bullet went where I sent it.
I went to eject the round, but it was stuck in the chamber, and the primer fell into the magazine well. A quick push with a cleaning rod got the brass out of the chamber easily, and then I noticed that the extractor had slipped off the ball detent on the bolt face. This probably explains why the round did not eject. I easily reset the extractor on the ball detent, and it now works 100%.
So, what happened? The load is on the mild side, the rifle and brass are new and good quality, so this should not have happened.
Is it possible that the extractor failed before firing the round, and the cartridge was not firmly against the bolt face when I fired it?
Any insight would be greatly appreciated.
