[QUOTE="azsugarbear, post: 773798, member: 4809"] Have your smith look at the bore with his scope. I had a custom .243 act the same way after 100 rounds. Turns out, in spite of my cleaning regimine, I had several layers of copper & carbon built up just past the throat area. I am meticulous with my cleaning, so I was very surprised. My gunsmith recommended a few passes (not more than 3 or 4) with JB's Bore Paste to loosen things up, then clean as before. My pressure problem went away. Just one more thing to check. [/QUOTE]
