In your place I’d be tempted to drop weight to get a shorter bullet, with the fringe benefits of higher speed, better stability and an allowance for the 1/10 barrel twist.
my experience is that 130gr copper is a 30 cal round, with 100-110gr being weights for .264. Assuming there’s some logic involved, 270 will be in between, with some overlap at the lower end.
worth a try?
