I vote for a 168 to 180 grain 7mm Accubond.
Make them as heavy as possible for factory rifles, such as the 9 1/2 twist REM 700 Sendero 7mm Ultra Mag.
This would be an ideal big game bullet in 7mm for Elk sized game. Similar to the 175 Nosler Partition, but an Accubond.
Working with factory twist rates would keep the sales volume high ...
