Greg it seems we get this stuff figured out...and the manufacturers throw us another curve...I can't keep up! grin

Am I off base, or does the real change come when bullets get a G1 BC over .600?

Below that stuff seems closely bunched. confused

I can say,recent shooting with a 150 BT and 162 Amax from the 7 RM and Mashburn out to 600 yards, the 162 behaves itself better....




The 280 Remington is overbore.

The 7 Rem Mag is over bore.
