[QUOTE="AkleyFan, post: 2867332, member: 114323"] I have a 30-06 that had a similar issue. The chamber was cut with a pull-through reamer typically used for chambering Garands/M1's. The chamber was tight, especially with range pick up brass FL resized with a standard sizing die. Most of my reloads were snug when chambering a loaded round and were difficult to extract after firing. The rounds that went in butter smooth did not act this way. My solution: I polished the chamber with an 800 grit flex-hone - checking the fit with various pieces of fired brass that I measured - I used them as a gauge to check fitment. I also purchased a small base circle FL sizing die and these problems are now behind me. All resized brass chambers without any tension and after firing extract without issue. The rear half of my chamber was honed .0015" larger, the length was within spec. It's a phenomenal shooter now and 100% reliable. I believe that the snug brass/chamber combination did not allow the brass to expand while firing which would have allowed it to rebound/contract to a smaller size - which would allow it to release itself from the chamber walls. Generally, firing the snug brass made extraction after firing even more difficult. Hope this helps. [/QUOTE]
