Run the 215 Berger at 3250 and run your numbers again. Compare apples to apples.For fun, I just put in the ballistics of what my "hunting" load in my 6PRC would be. 109 ELDM at 3350fps with N570. It has better ballistics (wind drift, drop, and impact velocity) out to 1000 yards, than a 215 Berger at 2900fps.
That's on the high end of 6mm performance, but not a sub par load for the 215 either (300 win mag speeds).
Thought that was interesting for sure.
I only have backcountry deer hunts this year, and they can offer some long shots and wild conditions, so I'm not sure I could convince myself to hunt with the 6 PRC for gathering more data. But it's nice to compare things. It's not quite as comparable to my 7-300 as it is to a 300 win though.
