[QUOTE="crazyhorse, post: 1835512, member: 3056"] This is a very important issue that will show itself as pressure when in fact its nothing of the sort! Any lube left on the brass OR in the chamber will cause the brass to flow under pressure creating what looks like pressure signs. I learned this the hard way one day when shooting a known safe load used in the same rifle many times with zero issues. All of a sudden I'm getting big time extractor marks and really flat primers but no sticky bolt lift. After shooting a couple more and really paying attention to the situation, I noticed all of the brass felt oily. I compared them to the unfired rounds in my box and they were completely dry. A moments pause caused me to remember cleaning the gun thoroughly after hunting in a hard rain a few weeks previous. I took a lot of care to get oil in every place the water may have got into but wasn't diligent enough to get the oil out like I should have done. After swabbing the chamber dry with a tight fitting, cotton patch wrapped brush it returned to normal with no sign of pressure. Lesson learned! [/QUOTE]
