How this for a FLAT SHOOTING round:

This is my .270 B&B Mag:

130gr Nosler Ballistic Tip with 83gr (max load) IMR-7828 at muzzle = 3,863 fps/4,309 fpe

100yds: +3.10" ; 3,633 fps/3,811 fpe
200yds: +5.11" ; 3,410 fps/3,357 fpe
300yds: +4.22" ; 3,196 fps/2,949 fpe
400yds: 0.00" ; 2,989 fps/2,580 fpe
500yds: -7.95" ; 2,790 fps/2,248 fpe
600yds: -20.28" ; 2,598 fps/1,949 fpe
700yds: -37.60" ; 2,415 fps/1,684 fpe
800yds: -60.82" ; 2,241 fps/1,450 fpe
900yds: -90.65" ; 2,077 fps/1,246 fpe
1000yds: -128.97" ; 1,920 fps/1,064 fpe

Now that is FLAT! Not nearly as powerful in terms of FPE as the 366DGW, but plenty of flat. Savage Arms has looked at this round a year or so ago, in the aspect of making a proprietary (?) Savage round out of it. As of now it is still in the air.
