and it's SD will increase accordingly.
Here is a link that will indicate the value of a higher SD. It's only a tool.
Use whatever terminal velocity you wish, but keep them equal.

Yes, but in order for the 30cal to match the sectional density of the 6.5 recoil goes way up. If you like heavy recoil that's fine, but recoil negatively affects accuracy no matter how big or bad you think you are. That's why guys who are shooting 338 lapuas aren't doing it with a Kimber Montana or Tikka T3 Lite.
With modern bullets we are getting knock down power in smaller packages.
