Andy,
I double checked the Barnes manual and the figures still stand. I compared a .270 at 3100 fps with a 130 gr. XLC bullet with a .300 at 3200 fps with a 150 gr. XLC. The .300 is in front of the .270 energy wise until 500 yards. At 500 yards, they are about even. After 500 yards, the .270 has 50 lbs/ft more of energy at 600 yards. The table ends at 600 yards.
The BC for the .270 is .466.
The BC for the .300 is .428.
I guess the BC is what makes the difference.
