Anyone have ballistics on this cartridge?

I have them posted here:

Bill,
Your site looked great and it was nice to finally have some info on the WSM's.
I was wondering if you knew the water capacity of the 270 or 7mm WSM case? I know the 300 is around 83 grains of water. I want to do a 6.5WSM but feel that the 300 is too much case. I want one that would hold about 70-74 grains water and was hoping the 270WSM case would be this size.
Thanks for the help,
PrimeTime

Primetime, thanks for the comliment. I have no idea about the capacity of either cartridge. I got the info off a sheet the Winchester rep handed me a few weeks back.
