[QUOTE="wwbrown, post: 2359222, member: 31392"] Unless the rifle has been difficult to open the bolt since you bought it 30 years I doubt it is primary extraction. The primary extraction would have been present the first time you fired it. I do not know the history of the 700's but did they have primary extraction problems that are so prevalent today 30 years ago? I thought the primary extraction problem was a more recent problem. Carbon ring is a possibility causing an increase in pressure, leading to .... How about you post some pics of your fired brass focusing on the case head. The case head will often exhibit issues that indicate high chamber pressure, like flow into the ejector, flat primers ... Take pics of a couple of case heads if you decide to take your camera out more is more better. Just my guesses, there are many on this site with more experience than I have I just build bolt guns and the occasional AR for my own use. [/QUOTE]
