My stepdad shoots 150 round nose core lokts in his 270 and swears by them. I used to shoot a ruger m77 270 and used 130 power points and fusions and was very pleased with accuracy but didn't like that the entrance and exit hole were the same size. If you handload I would try some 130 or 140 accubonds. If ballistic tips is what you like I would try some 150 nosler ballistic tips unless your shots will be very close and if that's the case I'd definitely go with the accubonds.
