That is 540 grain FN in a 470, correct?

I would be interested if the 540 grain FN is suitable for a double rifle with a 1:20 twist.

AS I understand the information on Gerhard's site, with the banded bullet you would actually be able to bump the load and velocity without a pressure increase.

Could you get the 540 grainer up to 2100-2150 fps without excess pressure?
