I also use 5 grain increments. However, be sure and shoot 3 shot groups at each level. Can't really get a good idea of how well that load will work without a 3 or more shot pattern.

have never used pellets, but those that do say that mixing the pellets is ok.

DVD: I bet you are getted charged up about going! I know I am. I leave on the 8th. Just went out for my last tune up at the range yesterday and my last 3 shot group was 1" at 80 yards. Hope I can shoot that well in the field. Good luck.
