Likely it would be too intelligent to start with a conservative load (say like 7.3 gr for a 200 gr GD) & work up to where you think you should stop.........but as I said, that logic might be too intelligent.

You would need to use 230 grain data since the Barnes is at least as long and would reduce case capacity at least as much. It is more about how deeply the bullets seats into the case.
