So, does modest charge compression lead quickly to erratic pressure? I've seen loads listed as 'compressed', but I don't know if these were manufacturer's published loads or those from 'some guy on the internet'. I understand peak pressure is sensitive to that initial volume in the case, but I'm wondering now not so much about that particular effect as I am charge compression, specifically.

Regardless of any of that, the Barnes bullet seems to have done an incredible job at that velocity and in that medium. In fact I'd go so far as to say Andrew's test indicates that just might be the sweet spot for that projectile. Not a 50,000 rpm fan blade I'd want to walk into.
