[QUOTE="Lefty7mmstw, post: 680858, member: 48043"] Same reason-- trapped crap Entirely different origin though-- as the case ruptures at the start of the firing cycle, a lot of partially burned powder and gas will get trapped, hence the soot and dent. I've seen these twice with the 7stw on brass that was worked for many cycles and a trim or to to much without retiring. A dent like that can happen from poor initial gas pressure too. I've had it with my 300 win with faster powders and light bullets(playing with 125 grain bullets and 4895). [/QUOTE]
