I took out my scout/squad out today and had some real bad issues with failure to extract. I'm talking a failure rate of greater than 30% out of 80 rounds. There was a time or three where I had to kick the charging handle with my boot to get the action to open. On those times, I would drop the mag and release the bolt to regrasp the fired case with the extractor in order to get it out of the gun. When the case wouldn't release from the chamber, I had to give it the boot literally. I was using South African ammo today and I don't think that the ammo is the sole cause. I have a feeling the extractor or something related to it is to blame. The rifle would try to double feed. The bolt would recoil back leaving the fired case in the chamber and move forward to try to feed the next round. Any one have any suggestions?
BIG +1 on the Otis kit... its all i use on my M1 garand and will use on my m14's when i get them.. If i went with a rod it would be a one piece such as a dewey or tipton rod that is coated and has a ball being handle (i have two 1 in .30 caliber and in .22 (for my AR-15's) along with bore guides... to me the usgi stuff is for emergencies only.. true the above rods will cost you 30.00 a swat but they are worth it.. the Otis can be had in many configurations... the most popular with M14 types being the DMR kit which is about 45.00 CMP has a real basic one for 30.00..
I've kept a close eye on that thread. I have a strong suspicion that the problem is in the chamber. I took a fired case and placed it in the chamber last night and closed the bolt. I litterally had to kick the bolt open again. I had to push the case into the chamber with my thumb to get it to seat prior to closing the bolt. It's hard for me to see deep in the chamber but, I think I might see some crud deep inside. We'll see. I figure the extractor is ok if it holds while kicking the chamber open. I have a .308 OTIS cleaning kit on the way along with a .308 chamber brush. I've had similar problems with my M249 SAW and various M-16A2's in the army and it is either an ammo issue or a dirty chamber issue. The charging handles on those have seen my boot a number of times. That's where I'll start. I noticed the extractor change in your thead didn't resolve the problem so, I'll look esle where for a solution and go from there.
