No Dan not out of ideas. 1 st thing I learned reloading up bp rounds is that you only change 1 thing at a time. I would first wipe the same way after each shot. If that didn't fix it, I'd then know it wasn't a problem. Make sure your technique was the same every shot (I've seen the groups you shoot) but self check your routine. My own experience with duplexing is not wide and far reaching but I did not think it enhanced accuracy. What kind of clearance do you have between the end of the fore end and the frt of the receiver?..mb
