At first glance, the ranges in your table look about right as far as my own experience is concerned. But a question I have is at what distance does the 243 bullet drop to 800 ft lbs, and how fast is it still traveling? I assume this is probably a 115 grain bullet?
Part of my question concerns the issue of hydrostatic shock. As I understand, this only occurs at about 2600 fps and above. If the 243 bullet is still above that, wouldn't this be an "apples and oranges" comparison - or am I off track here?
