AR-15 Extractor Problem?
I am having a problem with my Colt Match Target Rifle Model MT 6601 after firing between 5000 and 7000 rounds it developed a problem of failure to eject the spent brass from the chamber. The extractor does not damage the brass but pulls over the rim. I have installed new spring O-ring and extractor. The ammo I am using is my reloads using Remington brass Full length sized with 55 V-max bullets. Since the rounds chamber just fine I have not tried small base dies. I clean the chamber every time I clean the gun using a chamber brush and am at a loss as to what to replace next.
I have also fired Wolf ammo and S&B with the same problem. Normally it will stick a case after 60 to 90 rounds have been fired. The problem developed within the last 1000 rounds being fired
Any help would be appreciated
A good plan violently executed now is better than a perfect plan executed next week.
