I wouldn't.
Dangerous game is potentially dangerous.
For that reason, I would think a little harder on it before taking a .270 unless it was heavily loaded with a mono or 160gn Partition and I still wouldn't, because there are better options without compromising on rifle characteristics.
Lots of fish are caught on a 4 pound line. Not ideal, but it works a lot of times. If you are in an area with bigger than fry pan sized fish, why would plan a disadvantage by not planning for success or worse, safety?
