Here are some empties. The ones on top are WW factory 180 gr. loads. They chronoed between 2300 and 2400 fps. You can see some primer flattening there.

Below are some empty elk loads. They were 43.5 gr of AA 4350 behind a 200 Hornady RN. Primers were CCI and Remington. They chrono-ed around or below 2,000 fps. I've gone up to 42 H4350, but where we hunt 65 yards is a long shot.

I'm not convinced about the accuracy of my brother's cheap Chrono, but it detects a 10-20 fps variability in my black powder loads.
