Then, you will hit the expansion threshold of 2000 fps at roughly 230 yards as opposed to 200 yards if you are getting 2700 fps instead of 2600...
That is of course assuming that the BC reports of 0.277 and dxpansion threshold of 2000 fps are correct. It is entirely possible that the internet reports for those values are bogus and I have no means to verify them.

I like my rifles like my women - short, light, fast, brown, and suppressed.
