They are advertising the bc at .616. However, I agree the BC could be higher. If the nose is more aggressive like a berger it would require a longer OAL and not fit in short action/be finicky to reload. Winchester/Browning said wanted the heaviest/highest BC (min .6) could fit in a short action and get good velocity and not be finicky. There are already plenty of super long heavy 7mm bullets can do custom loading for in a long action. I am not advocating just stating what they said as their design parameters. As an example I have a 270 WSM 1-8 twist on Kimber action. With Berger 170 EOL to the lands with the berger is 3.06 (going from memory but it is at least 3.06). With the 175 Matrix it is 2.96 and incidentally the 165 ABLR is also 2.96. If optimize for BC, the ogive could be made longer but would be even longer jump to lands / finicky staying at 2.95" for cartridge.
