I’m having a strange malfunction in my .308win AR10 I’ve never seen or experienced (been shooting the gun for years). The casing would get stuck so tight in the chamber the extractor on the bolt would rip the extractor ring off the brass case. I had to knock the casing out with a cleaning rod to remove the case. Even with the cleaning rod it still took a good amount of force to get the case removed. This happened twice in 50 rounds. Even the cases that did remove properly the extractor ring was bent slightly. I did not see any extractor wipe or any blown primers on any of the casings.
My question is, was this caused by the rifle being dirty or was my load to hot. I was using sierra 175gr hpbt with 48gr Win760 at 2.80 COL. The load shot great just had those strange malfunctions. I pulled the bolt and extractor on the rifle and it was pretty dirty but did not look physically damaged/bent. Thanks for the advice! Also, I havnt ever used that exact load before.
