It was interesting shooting both chamberings/loads side-by-side. We had enough wind to make the wind drift/correction very visible.
The 270 had an MV advantage of about 370 fps, but the high BC on the 208 AMax really rode the wind better at all distances.
The 270 saved some elevation at all distances out to 1500. I think I was dialing about 3 more mils elevation on average, from about 900-1500.
Running some calcs in JBM, it looks like both of our bullets were retaining about 1520 fps at 1000 yards. The heavier bullet caused a visibly bigger splash way out there.
